A group 15 element forms $\mathrm{d} \pi-\mathrm{d} \pi$ bond with transition metals. It also forms hydride, which is a strongest base among the hydrides of other group members that form $\mathrm{d} \pi-\mathrm{d} \pi$ bond. The atomic number of the element is ____.
Solution
Phosphorus belongs to $15^{\text {th }}$ group and forms $\mathrm{d} \pi-\mathrm{d} \pi$ bond with transition metal and $\mathrm{PH}_3$ is strongest base among the other group members excepet $\mathrm{NH}_3$.
