Layne Compton · Answer 1

e. 18

Explanation:

A neutral P atom has an atomic number of 15, which means there are 15 protons in the atom. In order to be neutral, the P atom must also have 15 electrons.

The P³⁻ anion has 3 electrons more than the neutral P atom since it has a charge of - 3.

Thus, the total number of electrons are 15 + 3 = 18 electrons.
