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} $ .
