“The outer energy levels are full, but that doesn’t mean the inner ones are,” says a friend. How would you respond?

He is WRONG

Explanation:

Any atom at the ground state has its orbital levels fill from the bottom (close to the nucleus) – up. The inner orbitals are of lower energy state and fill first because the atoms ‘likes’ to exist in the low energy and more stable state. Only when the atom is in an excited state do some of the electrons in the lower orbital levels shift to higher unfilled orbitals.

yes you are doing it right great gob
