eventually you're recording she wants to do the first blank calculator alright we'll start with Crystal four C batteries all matter is made up of atoms Jamari what is it Dalton's atomic theory all right Miss Leona number two all continents that artist all the elements Antoine are you with us can you have two numbers okay Crystal can you do number three number three elements bonds to create compound compounds last but not least Mayana you do number for yes creative matter cannot be created or destroyed what else do you know one of Newton's Laws of something you learned it last year or shouldn't I'm not sure yeah what is it no I mean no maybe energy that sounds familiar baby energy alright so yeah matter and energy solid that same rule is follow the same rule I cannot be created or destroyed all right yesterday yesterday we decided we are investigated what exactly is matter what exactly is matter what do we know what is matter matter is anything that occupies space possesses Mass can be felt by one or more of our senses you're awesome yes thank you alright so Cola can write so we know matter is made up of atoms speaking of atoms we are going to investigate and find out exactly how to read a periodic table okay so looking at this diagram what do you see that is similar you see anything that looks the same between oxygen and nitrogen and I know we haven't talked about any of this yet or proton and neutron yeah okay that's one anyone else differences of similarities and difference nitrogen has seven and oxygen has eight so we're going to learn and we both have you electrons Mariana or Crystal can y'all find any similarities or differences ABC a picture of the red stuff in the gray so they both have right okay nitrogen is nitrogen a type of gas are both the type of gas so I don't think there's any more differences or similarities you don't know oxygen is an element or block at the top and nitrogen don't see that block. unblock electrons it has caused an electron on top still think about this one its outer shell has one more electrons in nitrogen speaking about what about that first that first discovered we haven't talked about it yet what about that first Circle how many electrons are in both of those there's two oxygen has more than nitrogen new record okay and a race all right all right so we know did you know she probably heard this multiple times the building blocks of life the building blocks of matter Adams right where is made up of atoms I was at our Gina matter is made up of atoms kind of like leggings think of every state Dewey you don't have to I'll let you know Minecraft so kind of think of Legos are building a building a structure with Legos each one of those Legos could represent an atom but of course atoms are billion times smaller than the Lego we're going to find out alright remember so this is from yesterday anything that has mass and takes up space is matter all right notes is the smallest possible unit you can think of I'll still make my still maintaining his properties what does that mean trying to see if we're just wanting my whole focus is for y'all to recognize the parts of the atom right right now I just the pieces of an atom have protons they all have electrons in all atoms Except for hydrogen neutrons hydrogen is the only element that does not have a neutron no Jimmy Neutron for hydrogen so imagine the sea that it was in the center is the Sun the electrons are circling or orbiting at Center like the Earth orbits the Sun to the protons and neutrons make up that Center and you're talking about does little black lines represents the electrons let me know when I turn it on by the way yesterday I added 5 of y'all to my student Spotlight on my website because y'all literally made my day yesterday's class was exactly what every class should be like some very proud of you I know we're all excited and ready for the weekend be a little bit more lenient today but not by much no I'm not all right just how small is an atom all right so imagine human hair and I'm talking about that's in that thin strand of hair we can find about 1 million carbon atoms wide that's 10 piece of hair is 1 million carbon atoms why fitting a million carbon atoms exact thin thin is a pear I'm going to write this down so don't try this you can write it down you don't have to but if it helps you find a few helps you to think about how small they are you can write it down okay so taking a grain of salt that you put on your eggs or your soup if you were to count all the atoms in a small grain of salt it'll probably take you five hundred years and that's including the hours of sleep that you take so yeah Adams are small oh yeah yeah so we are going to look at how I do look at his hair broken down breaking it down some more Play Store they were still in Webster New Hampshire don't have to see atoms yet all these little dots. what is the center of an atom Mary r so how slow do you think an atom is Greece Mall yeah yeah alright so let's break down the atom interest me parts we have are protons they are positive positive protons remember that because proton starting to pee like positives T like positive alright to help make up a new I just sent her that Mayana had noted earlier observed a make up the nucleus along with the neutrons they help identify the atom I'm going to show you that just a moment 30 equal to the atomic number of the atom I'm also going to explain that in a moment can you call to the number of electrons before you start writing down I'm going to here's a beautiful periodic table with all the elements let's look at Carbon up close the carbon is usually the numbers usually at the corner of here all right number at the corner is he atomic number do every element is labeled with a number 1 through 100 so you might have thought that the periodic table was just remembering the elements not some each one of these number represents the number of protons in an atom Carmen is the only element that has six protons it's the only element that has six protons potassium there's 19 Tascam is the only one that has 19 protons oxygen the only element that has 8 protons fluorine the only element again it's hammock number one in the corner equals number of prayer times bright sew in start talking about how these elements will bond to other elements an element cannot will not lose its proton it will not lose its proton cuz once it loses its Protime it completely changes its identity you say that again elements and Adam will not cuz when it does it completely loses its identity it becomes something else so they won't so when elements bond together they do not do not lose their protons they will never lose their presents that's what he say protons identify the atom the number of protons will tell you what kind of atom you're looking at is it oxygen carbon hydrogen question I can't hear you I said I cannot even can you can you can you get out can I make yes yes yes you may I can't see the Char you guys. So something out here we're looking at the periodic table where are suing it is you're going to assume that that is what the element will be like if it was neutral meaning it had no charge so the number protons is going to equal the number of electrons only if the atom is neutral if the atom is stable are excellent say carbon has six protons protons have a positive charge that means we're going to have if this carbon was neutral it has a negative charge cuz everyone knows 6 + 6 the positive 6 plus a negative 6 is going to give you 0 do if the atom was neutral it has to have equal protons and electrons we're going to be doing a lot of practice with this promise I know this is a lot of information last year my students had to do this virtually as well I was kind of hoping that we would do this unit a space cuz it's very difficult there's a lot of Hands-On stuff you can do with this lesson it makes it a lot easier to understand but we do what we got one day I'll be able to do this unit face-to-face hold on a second water games are you still write notes are we good good okay that's a mess Antoine. Antoine yep all right we'll see you I'm recording this lesson so you'll be able to pick it up for my website okay Macy's Covington I didn't get to see who wear your star student who were they who were your star student I play all of those names yesterday responding you were participating y'all didn't give me any delay when I was asking so I started the entire class because I was I was I was I was I was very very very impressed yesterday just a moment okay we have no electric charge you can always remember that Nissan's have zero charge because they say sound like neutral neutral neutral write 0 charge I also helped make up the nucleus and contribute to the atomic mass let me know when I can move on I'm going to say the hydrogen atom hydrogen 0 neutrons the only atom on the periodic table that has zero neutrons Adrian is a special case I did and it's also extremely reactive hydrogen is hardly is never found by itself so it's always bonded to somebody else if it is found by itself is not very long what you doing tapping my pencil alright cool alright youngest you ladies if y'all all right so again can you please set the Adam makes up the center notice that the electrons are not messy electrons are not in the center so the nucleus Eagles prayer times and electric and neutrons all right last but not least we had our Electronics are found outside of the nucleus in orbiting level they orbit they are continuously around the beautiful Center be called a nucleus is protons and neutrons are so tightly packed together so tightly packed that they do not separate they are completely okay by themselves electrons on the other hand these guys are middle schooler on sugar all right artist Covington a lots of lots of sugar you think I'll walk around you think of walk around a lot in your class by Journey on sugar I just got my eyes are going fast they are so small their mass is so insignificant like literally so you okay I'm just talkin about an atom you talk about it snacks electrons neutrons protons but the electrons mass is so insignificant it's so small we usually don't we don't consider it when talking about the mass Seattle Brian is the reason why it's the reason why you see on the periodic table these numbers with decimal points okay these electrons who don't consider these electrons because they're so minuscule okay so when we're talking about the mass we're going to round up oxygen that's not what I want is oxygen 15.9994 what around that up to 16 and say oxygen has a has a mass of 16 arsenic mass of 75 Sunny 4.9 excetera we round up or round down 8011 we're going around that to just 12 so electrons were going to use to make chemical bonds a neutral atom just like we said number of protons equals number of electrons negative charge outside the nucleus an electron orbits clouds bass is extremely insignificant that we do not consider it let me know when I turn it on don't worry about this part this part a little bit later okay don't worry about that part so in summation we got three rules when trying to take a part okay atomic number equals the number of protons atomic mass we don't consider the electrons because they're so small we're going to only use protons and neutrons to calculate the mass if the atom was neutral the number of protons equals the number of electrons in this case he has 6 protons this is the number of electrons that he equal -6 electrons is going to give us a zero charge neutral charge all right so when you look at the periodic table the number at the top tells you the number number at the bottom the atomic Max Okay so Mass number John's neutrons all right all right you know first what is the atomic mass of carbon 12.01 12.1 Crystal atomic number was number carbon I think was 7 weight okay Mayana how many protons does Carbon have David Harris it has maybe six is Antoine with us can you tell me can you can you tell me the number of neutrons how many neutrons does carbon have I think he's a cyborg Microsoft did not work and that's what it's like a glitch or something someone else 0 atomic mass number and atomic mass equals protons and neutrons so he's home at 12 that means we have 6 protons 6 neutrons alright are we always going to have equal protons and neutrons nope this case yes all right do you want somebody electrons how many electrons are we going to have 6 make a little bit more sense yes yes okay yes alright we're going to skip this because this so we're not going to we're not going to worry about building the atomic model right now I just want y'all to get familiar with atomic mass atomic number electrons neutrons protons building atomic model be much much easier okay so we're only going to worry about find the mass finding b not the atomic number how many electrons neutrons and protons okay next week we'll focus atomic model so what's your Boron helium's too easy alright Tomic mass of what is the atomic number of boron Crystal atomic number of boron 11 call baby girl bye 11:11 number of the corner atomic number all right I know these words it's fine it's easy to get the next up all right protons how many protons do we have Jamari Florida does it show it on the so again, number is 5 atomic mass is 11 how many protons do we have 5 okay so neutrons electrons all right Brianna how many neutrons do we have let me see everything what does atomic mass equal what are the what two parts of the atom do they use to find atomic mass videos that would be used to hold on atomic mass equals blank plus blank does a maybe 6 neutrons or no I'm figuring out good yes how do you find honestly I cast forgot atomic mass equals the number of protons plus the number of what I did have 11 off of 11 Define the number of neutrons please first look at our atomic number okay our Tomic number is 5 and since atomic number meetings number crush on you can put that in your equation now numbers to you look at the atomic mass the atomic mass is 11 11 equals 5 + what 6 does 11 - 5 equal 6 right I said I thought it would be -6 to make 6 I'm at 12 looking at Carbon all right so we are looking at boron the boring boron all right so we know we had five from times that would give us six neutrons 5 x + 6 neutrons equals atomic number atomic mass of 11 what time is it so tell me the time 317 I think when you look at more practice all right cuz everyone is everyone time understanding what's Howard Mass which one is atomic mass which one is the number yes y'all can get that you got you somewhere alright just takes a little bit more okay discard is talking to me all right that's not what I wanted do rainbows cuz I like rainbows Etsy spring hurry up here in a 7 down here stop it directions all right Rihanna what is the atomic number of lithium the atomic number of what lithium I came to see you nephew flash boy so the number and the is the atomic number the number on the bottom is the atomic mass so we're looking for the atomic number looking for the number in the corner SO3 all right Islamic mass is what tomorrow 7 misscrystal how many protons do we have can I have a bird I think it's a 3 Jamari yeah she just read your mind alright then you'd have a little bit more patience I had a feeling crystal is going to get it yes it is 3:00 so assuming that lithium is neutral it's very stable electrons does lithium have Crystal how many electrons has 7 what's the mass of the mass so one of our rules one of our rules states that the number of protons equals the number of electrons when the atom is neutral we are assuming lithium is neutral so how many electrons does lithium going to have if its protons are in 3 it's going to be 3 since we think it's new yes ma'am three times this is where you were messing up so you get to do this problem I know it stinks when a teacher actually tries to get you to learn something atomic mass the problem equals what plus what 7 + 3 what does atomic mass equal two parts of the atom do we add together they have three parts to the we use for the mass what parts do we add do not listen to my words do we add protons electrons and neutrons which two do we add to get the atomic proton plus neutrons which monster mass is so insignificant we don't we just don't consider it ask equals protons plus neutrons alright so you know our comic mass is 7 the number of protons is what Maya Appleton estate times blank how many neutrons do we have 3 plus what equals 7 or yes you got it yes all right so reason why I was being particular about about putting the problem together because if you understand the rules then you can start all right so the rule atomic mass equals protons plus neutrons are so small we just meet me leaving out of the equation just say goodbye and we don't care about you the mass is okay without the mass protons plus neutrons all right once you have that formula then you can start plugging in the numbers and it makes everything a lot easier you know the atomic number was seven know that the number of protons free because our Tomic number was three all we need to know his number of neutrons easy easy Crazer 7 - 3 equals 4 or neutrons make sense baby make a little sense more sense Instagram all right y'all want to do another one together before I send you off to class work yeah cannabis seeds your music Bermuda Mustafa team you're muted again go back now okay let me know if I get neutered again you're muted again meeting you for some reason is there anyone who is meeting me no I'm not a sir all right write my nearest Stihl no let's figure it out what is the atomic number for chlorine 17 atomic mass yes we have 17 protons in a neutral chlorine atom how many electrons are going to have 17 you guys rock all right neutrons me did you want to try this hello Chris Gardner are you with us want to try this whenever you want to give it to somebody else I can't see it lunch or do you want to try the number of neutrons if you want to give it to somebody else the number of neutrons so would it be so it would you do protons edit bus electrons not electrons remember electrons we don't consider electrons in the mass protons plus what proton neutron all right with Sony PlayStation how many protons do we have 1717 do we have to how do you make 17 so how would you get the number of neutrons Pringles set at going to put an X right here so this is a basic math problem how we going to get neutrons by itself is it 80 is it you got it cuz where I'm trying to do is get 17 I meant 35 from 17 it is yeah he confident all right I'd be confident in your answers okay all right we have 7 and 12 minutes left okay we could do one more together or I can show you what the homework is that's due for Wednesday we can do the homework somewhere at the zoo for Wednesday alright okay what did this miss here I was going to stop recording
