Question

Explain Pauli's exclusion principle.​

Answer 1

$\huge{ \red{ \underline{ \underline{ \mathfrak{ \red{Answer:-}}}}}}$

Pauli's Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, (1) no more than two electrons can occupy the same orbital and (2) two electrons in the same orbital must have opposite spins (Figure 46(i) and (ii)).

Answer 2

Answer:

Paul's Exclusion principle: "No two electrons in the same atom can have all the four quantum numbers the same".

Illustration: In s-orbital, there are two electrons, the set of the quantum numbers of one electron differ with another in spin quantum number.
