Question

State and explain pauli's exclusion

Answer 1

Pauli's exclusion principle states that no two electrons in an atom can have all the four quantum numbers equal, which means that at least one of the four things (energy level, orbital, magnetic movement, spin) has to be different.

Answer 2

Pauli Exclusion Principle.

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 spins.
