Question
why is the atomic radius of Mg2+ bigger than that of Na+?
 Question Submitted By :: Inorganic-Chemistry
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
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
# 2
atomic radius of Mg2+ is not bigger.
the one with larger positive nuclear charge will have
smaller radius.
so its radius is small.

Answer
# 3
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
 
Is This Answer Correct ?    9 Yes 2 No

Answer
# 4
in periods atomic radius decreases with in creasing atomic
number.
 
Is This Answer Correct ?    1 Yes 22 No
Prasad
 
Answer
# 5
as the mass no of Mg2+ is more than Na+ 
Is This Answer Correct ?    7 Yes 33 No
