Pauli's Exclusion Principle:
- The Pauli exclusion principle states that no two electrons in an atom can have the same set of quantum numbers.
- This means that each orbital can only hold two electrons, with opposite spins.
- The Pauli exclusion principle helps to explain the stability of atoms and their electronic configurations.
- Without the exclusion principle, electrons would occupy the same orbital and would experience mutual repulsion, leading to an unstable atom.
