Question

what is pauli's principle​

Answer 1

Answer:

The Pauli's Exclusion Principle was given by Wolfgang Pauli in 1926. This principle actually excldes the possibility of any two electrons having all the same four Quantum no. i.e. 'No two electrons in an atom can have same set of four quantum no.'

This principle helps us to find the maximum number of electrons which can be present in a particular subshell.

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.
