In a given atom no two electrons can have the same values for all

In a given atom no two electrons can have the same values for all the four quantum numbers.This is called

Options

(a) Hund’s Rule
(b) Aufbau principle
(c) Uncertainty principle
(d) Pauli’s Exclusion principle

Correct Answer:

Pauli’s Exclusion principle

Explanation:

No two electrons in an atom can have same values of all the four quantum numbers: e.g = 1s²
For Ist electron n = 1 , l = 0 , m = 0 , s = + 1 /2
For II nd electron n = 1 , l = 0 , m = 0 , s = – 1 /2.
