Answer Posted / pablo
as in answer # 4 was explained... the question is wrong.
They both have 10 electrons with the configuration of Neon:
2s2 2p6 and empty 3 s
but Na+ has only 1 proton whereas Mg+2 has two--
therefore Mg+2 has a smaller atomic radius then Na+
This can be verified in any decent highschool chemistry book--
By the way, I'm a real chemist! Whoever marked any answer in
this page (except for # 4) as correct is INCREDIBLY WRONG
