Phosphorus has a partially filled 3rd principal energy level with 2 electrons in the 3s and one in the 3p orbital. So the answer is 8.
235815
The fourth energy level has 18 electrons. The fourth energy level of the periodic table includes the 4s 3d and 4p orbitals. The 4p orbital holds 6 electrons.
