Which of the following alkali metals reacts directly with nitrogen?

Identify the basic oxide from the following.

The $s$-block elements are characterised by their larger atomic sizes,lower ionisation enthalpies,invariable $+1$ oxidation state and solubilities of their oxosalts. In the light of these features,describe the nature of their oxides,halides and oxosalts.

Two metals $A$ and $B$ having similar ionic radii,react with oxygen to give only monoxides and react with nitrogen to give nitrides. Then,$A$ and $B$ respectively are

When sodium is burnt in moist air,the final product will be:
