you guys have your number already write your atomic number  that is going to tell you what element you have queso the number that we generated on the on the program go look for it and you guys have to K you're the only class it's doing to all the other classes Doin What go look to see how much information you can get off of the periodic table k your atomic number  here's your protons add your electrons can my brother the ape man thing that we did this is where you're going to need it off of the periodic table you can find atomic mass and I want you guys to do something with the mask pay very close attention look at the mass that you have for your element whenever you're working with the model like this we're only going to use whole numbers K we're not going to use decimals so I need you guys to stop your number of your mat why are you rounding it up or let me show you what  the reason you're rounding it up is because  here at Tomic mass is your nucleus if you have one 24.3 you can't have you cannot have .3 of a bead you've got to have the whole number because the mass is the protons and the neutrons case round your number for the mess  your neutrons this is for you use the man of the ape man man to find the neutrons you take the mass  can you subtract the atomic number now here's the important part right here case will pay attention if you have your periodic table all your periodic table you have periods right here look to see where your element is and the kids go across their like the x-axis and math  so let's say for example I think Xavier you got calcium right or somebody got Counting okay well you got calcium anybody got calcium bed say that you're looking at calcium it's in. Number for so that means that you're going to make for rings that is what the. Means the. Tells you how many rings you have in the electron cloud so it was our to give you this on a test Anne Archer ask you what Pier does this element in what parrot is this element in  . 1 2 3 because it has 3 rings  now the next in the cheetah fill out on your paper is the group or the family take a look at the number at the very top of the call if you have a number with the letter 1A 2A 3A 3B for B put that with the letter right here David Square put the number K. Put the name of the family put the number  now very important this is very important for should pay attention if you got an element  and some of you did you got an element that's in the orange don't worry about valence electrons right now if you have an element that has an a like 1A 2A 384-858-6878 you can fill in the number of valence electrons right now  the number of valence electrons is number next to the letter only if you have the egg group  zappy groups are different K don't fill in the electrons for the big groups yet what number is the number at the top right here you see how this one has an a number play right next to a toaster these guys have one valence electron these guys have to we don't do the orange ones because these guys have different numbers but you go over to the three a these guys have three these have for these have 5 6 7 and 8  nobody got helium soul going to have an issue with that one  the next one take a look at your border  see if your element is to the after to the right of the border and then fill in what it is it's a metal or nonmetal  take a look at your box of your element if your element has an X inside of it it's a it's a gas  David has a slash it's a liquid China there's nothing inside of it it's a solid not for the next one how many rings does your Adam have all you have to do is look at the period number if your impaired number 3 it has three rings. For four rings. Five five rings
