Concept introduction:
Electronic configuration can be assigned to any elements in ground when they follow certain rules like Hund rule, Pauli Exclusion Principle and Aufbau rule. If
No two electrons in an atom can have same group of four quantum numbers and this is Pauli Exclusion Principle.
While filling of orbital’s, electron first enters to each energy level with degenerate energy before paring of electron begins and this is Hund’s rules.

Answer to Problem 37A
Complete electronic configuration of Magnesium with
Explanation of Solution
As per Aufbau rule electrons are filled in lower energy orbitals that are closer to the nucleus before they are filled in higher energy ones. The order of orbital arranged in their increasing energies is as follows:
So complete electronic configuration of Magnesium with
