Answer
Pauli's Exclusion Principle states that no two electrons can have the same values of the four quantum numbers in an atom.
Work Step by Step
Pauli's Exclusion Principle is a principle which states that in an atom, an electron can be uniquely assigned a set of four quantum numbers.
It can also be stated as- No two electrons can have the same set of the four quantum numbers.
Even if two electrons are in the same principle shell (say 3) and have the same subshell, (say s), then their magnetic spins are bound to be different.
