Atomic Structure Question 249
Question: Which of the following ions is not having the configuration of neon
Options:
A) $ {F^{-}} $
B) $ M{g^{+2}} $
C) $ N{a^{+}} $
D) $ C{l^{-}} $
Show Answer
Answer:
Correct Answer: D
Solution:
Configuration of $ Ne $ = $ 1s^{2},2s^{2}2p^{6} $
$ {F^{-}} $ = $ 1s^{2},2s^{2}2p^{6} $
$ N{a^{+}} $ = $ 1s^{2},2s^{2}2p^{6} $
$ M{g^{++}} $ = $ 1s^{2},2s^{2}2p^{6} $
$ C{l^{-}} $ = $ 1s^{2},2s^{2}2p^{6}3s^{2}3p^{6} $ .
