Question

state and explain Pauli's exclusion principle​

Answer 1

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:

The Pauli exclusion principle states that in a single atom no two electrons will have an identical set or the same quantum numbers (n, l, ml, and ms). To put it in simple terms, every electron should have or be in its own unique state (singlet state).

Explanation:

Rules:

1. Only two electrons can occupy the same orbital.
2. The two electrons that are present in the same orbital must have opposite spins or they should be antiparallel
