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.
