Which of the following alkali metal nitrates on heating decomposes to give ${\mathrm{NO}}_2$ gas?

Which of the following does not illustrate the anomalous properties of lithium?

For which of the following property, diagonal relationship between beryllium and aluminium is not responsible?

Beryllium and aluminium exhibit many properties which are similar. But the two elements differ in

$\mathrm{BeO}+\mathrm{C}+{\mathrm{Cl}}_2\stackrel{600-800\mathrm{K}}{\rightleftharpoons }\text{'}\mathrm{X}\text{'}+\text{'}\mathrm{Y}\text{'}$

$\text{'}\mathrm{X}\text{'} + {\mathrm{LiAlH}}_4\to {\mathrm{BeH}}_2 + \mathrm{LiCl} + {\mathrm{AlCl}}_3$

The oxidation state of non metal in compound X is

Which of the following is not correct?

In the periodic table, the relations between $\mathrm{Li}-\mathrm{Mg},\mathrm{ }\mathrm{Be}-\mathrm{Al},\mathrm{ }\mathrm{B}-\mathrm{Si}$ are called diagonal relationship. These pairs of elements show similarities in their physical and chemical properties. The factor responsible for this is
