The electron configuration of a phosphide ion (P³⁻) is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶. Therefore, the correct electron count for all four energy levels of the phosphide ion would be:
1st energy level (n=1): 2 electrons
2nd energy level (n=2): 8 electrons
3rd energy level (n=3): 18 electrons
4th energy level (n=4): 8 electrons
So, the total electron count for all four energy levels of the phosphide ion would be 36 electrons.
