The Pauli Exclusion Principle is related to the quantum numbers of electrons. It states that no two electrons in an atom can have the same set of four quantum numbers (principal quantum number, azimuthal quantum number, magnetic quantum number, and spin quantum number). This principle is important in determining the electron configuration of atoms and the properties of chemical bonds between atoms. In simple terms, it means that electrons have to occupy different energy levels and different positions within those energy levels in order to form stable atoms and molecules.
