Answer / patrick
Its not. Both Na+ and Mg2+ have the same number of electrons
in a configuration emulating Neon, the difference is Mg has
more protons in the nucleus attracting the electrons inward
thereby making Mg have a SMALLER atomic radius.

Answer / sana.rampur
atomic radius of Mg2+ is not bigger.
the one with larger positive nuclear charge will have
smaller radius.
so its radius is small.

Answer / 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
