(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.
