$Li_3N$

Vedclass · Answer

(B) Among the alkali metals,only $Li$ forms a stable nitride $(Li_3N)$ by direct reaction with nitrogen. This is due to the high lattice energy of $Li_3N$ resulting from the small size of the $Li^+$ ion. As the size of the alkali metal cation increases down the group,the lattice energy decreases,making the nitrides of $Na, K, Rb,$ and $Cs$ unstable with respect to decomposition into their elements.
