How can you synthesize nitric oxide $(NO)$ in the laboratory?

White phosphorus on reaction with concentrated $NaOH$ solution in an inert atmosphere of $CO_{2}$ gives phosphine and compound $(X)$. $(X)$ on acidification with $HCl$ gives compound $(Y)$. The basicity of compound $(Y)$ is

Consider the following Assertion $(A)$: Phosphorus can form both phosphorus$(III)$ and phosphorus$(V)$ chlorides, but nitrogen cannot form nitrogen$(V)$ chloride. Reason $(R)$: The electronegativity of nitrogen is more than that of phosphorus. The correct answer is

Nitrous oxide $(N_2O)$:

The atomic number of $N$ is $7$. The atomic number of the $3$rd member of the nitrogen family is:
