Pauli's exclusion principle states that :
(1) Nucleus of an atom contains no negative charge
(2) Electrons move in circular orbits around the nucleus
(3) Electrons occupy orbitals of lowest energy
(4) All the four quantum numbers of two electrons in an atom cannot be equal
Ans: All the four quantum numbers of two electrons in an atom cannot be equal
