Question
Indicate electron configuration of Mn3+ ion. (Mn = 25).
- [Ar]4s2 3d10
- [Ar]4s2 3d2
- [Ar]3d5
- [Ar]3d4
Hint:
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
