Question

The electronic configuration of an element is $1s^2,2s^{2}2p^6,3s^{2}3p^{6}3d^5,4s^1$

This represents its:

• A. excited state
• B. ground state
• C. cationic state
• D. anionic state

Answer 1

Answer: (B), (C)

The correct options are
B ground state
C cationic state

The given electronic configuration is- $1s^2,2s^{2}2p^6,3s^{2}3p^{6}3d^5,4s^1$

it represents ground state configuration of Cr and cationic configuration of $M{n}^{+}$.

So, both (B) and (C) are correct.
