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)
