Depending on the period and group it’s in on the periodic table?
So, they are both in group 7 , but chlorine is in period 3 and fluorine period 2? So how would I use that to determine which is smaller or bigger and why??

Chlorine has an additional shell of electrons compared to fluorine so is bigger.
