The Pauli Exclusion Principle

Bohr's atomic model from 1913 described electrons in shells. Austrian physicist Wolfgang Pauli later proposed that a special property of electrons makes it possible for the shells to be filled up.

How important is it that electrons follow the Pauli principle? Does it only affect the structure of atoms? The answer is no. If electrons did not follow the Pauli principle, nothing would be able to exist.
