The electronic configuration

1{s^2},2{s^2}2{p^6},3{s^1}3{p^1}

correctly describes:

View answer and explanation

Correct option: C

Excited state of Mg

The correct answer is C (Excited state of Mg) because the ground state of Mg is

1s^22s^22p^63s^2

, and the given configuration has one electron promoted from 3s to 3p.
