Answer is k i.e potassium

Answer 2

Heyy

It's sneha

Here is ur answer

Comparison of atoms with ions_
K (potassium) and Br (Bromine) have large size than k+ and Br+ bcoz the + sign on k and Br shows that they both loses an electron which led to decrease in there size as nuvlear charge increases. So we can say that K and Br have large size than k+ and Br+


Comparison of atom with atom_
But if we compare size of bromine and potassium the potassium have large size of 280pm whereas bromine has size of 185pm

Hope it helps
