The 4 orbitals are

• s, p, d, f

• a, b, c, d

What does Hund's rule states ?

• states that single electrons electrons with the same spin must occupy each-energy orbital before additional electrons with opposite spins can occupy the same orbitals

• states that each electron occupies the lowest energy orbital available
  

• states that a maximum of two electrons can occupy a single atomic orbital, but if only if the electros have opposite spins
