Question

Indicate electron configuration of Mn3+ ion. (Mn = 25).

  1. [Ar]4s2 3d10
  2. [Ar]4s2 3d2
  3. [Ar]3d5
  4. [Ar]3d4

hintHint:

The electronic configuration is nothing but how electrons are distributed. It tells us how electrons are distributed in different atomic orbitals.

The correct answer is: [Ar]3d4


    the electron configuration of Mn3+ ion. (Mn = 25) : [Ar]3d4
