how to use the periodic table
are periods vertical or horizontal
horizontal
what subatomic particles change charge
electrons and protons
how many protons does sodium have
11
how many protons does oxygen have
8
how many protons does argon have
18
are groups vertical or horizontal
vertical
when it says atomic mass on the table, what does it actually mean
avarage of the atomic mass of all versions of that atoms in the universe (isotopes and non isotopes)
how many orbital shells does carbon have
2
how many orbital shells does neon have
2
how many orbital shells does silicon have
3
where is the name of the element located in a square
below the symbol in the middle
how do you find the amount of neutrons in an element on the PTE
atomic mass minus the atomic number gets you the avarage.
how many valance electons does boron has
3
how many valance electrons does titrogen have
5
how many valance electrons does chorine have
7
where is the atomic number located in a square.
top left
what atoms affect the atomic mass
neutrons and protons. "technically" electrons do, but they weigh so little that they are not counted towards the mass.
what is platinum's symbol
Pt
What is Rhenium's symbol
What is calcium's symbol
Ca
where is the atomic mass located in a square
top right.
how do you find the amoun of electons using the PTE
since all squares on the periodic table are neutral, there are the same amount of electrons as there are protons (atomic number).
how many neutrons on avarage are in helium
2.00260
how many neutrons are on avarage on magnesium
12.305
how many neutrons are on avarage in phosphorus
15.973
