Question

State and explain paulis exclusion principle in short

Answer 1

Answer:

Pauli's exclusion principle tells that none of the two electrons can have the same set of four Quantum numbers

or, two electrons present in the same orbital must have opposite spins

Answer 2

Answer:

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). There are two salient rules that the Pauli Exclusion Principle follows:

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 it should be antiparallel.

However, Pauli Exclusion Principle does not only apply to electrons. It applies to other particles of half-integer spin such as fermions. It is not relevant for particles with an integer spin such as bosons which have symmetric wave functions. Moreover, bosons can share or have the same quantum states, unlike fermions. As far as the nomenclature goes, fermions are named after the Fermi–Dirac statistical distribution that they follow. Bosons, on the other hand, get their name from the Bose-Einstein distribution function.
