What is the significance of the Pauli Exclusion Principle in electron configuration?

• It dictates the maximum number of electrons in an atom.

• It states that no two electrons can have the same set of four quantum numbers.

• It describes the sequence in which orbitals are filled.

• It determines the spin of electrons in an orbital.
