The ion that will be formed by the phosphorus atom when it has a stable set of valence electrons is . 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 .
