Explanation of Solution
Given electronic configuration,
Electron filling concepts in orbitals:
- Electrons first occupy the orbitals with lower energy than the orbitals with higher energy (Aufbau principle).
- An orbital can be occupied only by two electrons having opposite spins (Pauli exclusion principle).
- Each electron fills each orbital till it is half filled, when they are degenerate orbital (Hund’s rule).
The order of electrons filling in a multi-electron atom is given as follows,
