Vedclass · Answer

(C) Among the alkali metals,$Lithium$ $(Li)$ is unique because it reacts with atmospheric nitrogen to form a nitride $(Li_3N)$,whereas other alkali metals like $Sodium$ $(Na)$ do not form nitrides under normal conditions.Both $Li$ and $Na$ form oxides when burnt in air.Therefore,$A$ is $Na$ and $B$ is $Li$ (or vice versa depending on the context of the question,but here $Li$ is the one forming the nitride).Given the options,$Li$ and $Na$ represent the pair where one forms a nitride and both form oxides.

To distinguish between $A$ and $B$,it is observed that both elements form oxides. When burnt in air,$B$ also forms a nitride. What are $A$ and $B$?
