Atomic Structure Question 77
Question: Isoelectronic species are [EAMCET 1989]
Options:
A) $ {K^{+}},,C{l^{-}} $
B) $ N{a^{+}},,C{l^{-}} $
C) $ Na,,Ar $
D) $ N{a^{+}},,Ar $
Show Answer
Answer:
Correct Answer: A
Solution:
$ {K^{+}}=,1s^{2},2s^{2}2p^{6}3s^{2}3p^{6} $
$ C{l^{-}}=,1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}. $
