Solution
The correct option is B All of the above
The electronic configuration of an atom/ion can be defined by the following rules
(A) Aufbau principle
In the ground state of the atoms, the orbitals are filled with electrons in order of increasing energy.
(B) Pauli's exclusion principle
Two electrons in atom cannot have the same set of all four quantum numbers.
(C) Hund's rule of maximum multiplicity
When several orbitals of equal energy are available, the electrons first fill all the orbitals singly before pairing in any of these orbitals.
