Quantum Theory and the Atom

The statement that no two electrons in the same atom can have the same four quantum numbers is

• the Pauli exclusion principle.

• Hund's rule.

• Bohr's law.

• the Aufbau principle.

If an electron moves from lower energy level to higher energy level it is called

• ground state

• excited state

• neutral state
