Question

State and explain PAULI EXCLUSION PRINCIPLE ​

Answer 1

Answer:

The Pauli exclusion principle is the quantum mechanical principle which states that two or more identical fermions (particles with half-integer spin) cannot occupy the same quantum state within a quantum system simultaneously. This principle was formulated by Austrian physicist Wolfgang Pauli in 1925 for electrons, and later extended to all fermions with his spin–statistics theorem of 1940.

Answer 2

Answer:

The Pauli Exclusion Principle states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spinsPauli's Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. ...
