Atomic Structure Question 102
Question: Which one of the following groupings represents a collection of isoelectronic species [AIEEE 2003]
Options:
A) $ N{a^{+}},,C{a^{2+}},M{g^{2+}} $
B) $ {N^{3-}},,{F^{-}},,N{a^{+}} $
C) $ Be,,A{l^{3+}},,C{l^{-}} $
D) $ C{a^{2+}},,C{s^{+}},,Br $
Show Answer
Answer:
Correct Answer: B
Solution:
$ {N^{3-}},{F^{-}} $ and $ N{a^{+}} $ (These three ions have $ {e^{-}}=10 $ , hence they are isoelectronic)
