The ion that will be formed by the phosphorus atom when it has a stable set of valence electrons is \[{P^{3 - }}\]. Thus, the correct option is D.  

Explanation:

  • Phosphorus has the atomic number 15.
  • The shell electronic configuration of the phosphorus atom is 2, 8, 5.
  • It has 5 electrons in its outermost shell, i.e. it has 5 valence electrons.
  • It requires 3 more electrons to complete its octet.
  • Therefore, it has a tendency to gain three more electrons. It has a valency 3.
  • If an atom gains an electron, it acquires a negative charge.
  • Therefore, if the phosphorus atom gains 3 electrons to have a  stable set of valence electrons, it will acquire a 3 unit negative charge.
  • Thus, the ion formed will be \[{P^{3 - }}\].
