Detailed explanation-1: -Pauli’s Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, (1) no more than two electrons can occupy the same orbital and (2) two electrons in the same orbital must have opposite spins (Figure 46(i) and (ii)).

Detailed explanation-2: -We can only constructs wavefunctions that are antisymmetric with respect to permutation symmetry only if each electron is described by a different function. The Pauli Exclusion Principle is simply the requirement that the wavefunction be antisymmetric for electrons, since they are fermions.

Detailed explanation-3: -Pauli exclusion principle states that no two identical electrons (fermions) can have the same quantum state. Bosons, which have integer values of spin do not obey the Pauli exclusion principle.

Detailed explanation-4: -Aufbau Principle-This principle states that electrons will occupy lower-energy orbitals before moving on to higher-energy orbitals. Pauli Exclusion Principle-According to the Pauli exclusion principle, an orbital can only hold a maximum of two electrons with opposing spins.

Detailed explanation-5: -In quantum mechanics, the Pauli exclusion principle states that two or more identical particles with half-integer spins (i.e. fermions) cannot occupy the same quantum state within a quantum system simultaneously.
