Answer 2

Answer:

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 spinsThe anomalous Zeeman effect is the more general case. where the electron spins do not cancel each other and the. energy of an atomic state in a magnetic field depends on both. the magnetic moments of electron orbit and electron spin. The magnetic moment of the orbital angular momentum.
