The type of oxide formed by the element among $\mathrm{Li}, \mathrm{Na}, \mathrm{Be}, \mathrm{Mg}, \mathrm{B}$ and Al that has the least atomic radius is :
$\mathrm{A}_2 \mathrm{O}$
$\mathrm{A}_2 \mathrm{O}_3$
$\mathrm{AO}_2$
$\mathrm{AO}$
Solution
Among given atoms, Boron has least atomic radius oxide of Boron $=\mathrm{B}_2 \mathrm{O}_3$
