electrons
number of protons determines place in periodic table
- number of electrons is same as number of neutrons
arranged in shells at different distances around the nucleus
- proton number increases by one for each element
number of electrons in outer shell determines the group theyre in
- group zero is an exception because it comes after seven, usually having 8 electrons in the outer shell, except helium which has 2
- period number = how many shells there are, group number - how many electrons in outer shell
- group zero is an exception because it comes after seven, usually having 8 electrons in the outer shell, except helium which has 2
