Pauli Exclusion Principle
No two electrons in an atom can have the same set of all the four quantum numbers.
Two electrons can have the same value of three quantum numbers n, l, and me, but must have the opposite spin quantum number (s).
The maximum number of electrons in the shell with the principal quantum number n is equal to 2n2.

◆pauli's exclusion principle:-
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.
