Chapter 24, Problem 8QP

Interpretation Introduction

Interpretation:

The interstitial hydrides are to be explained.

Concept introduction:

Hydrogen is known to be first element of the periodic table. It is also the lightest element.

Hydrogen contains one electron and one proton.

Its atomic form exists only at high temperatures.

Hydrogen forms more compounds as compared to the other elements.

The ground state electronic configuration of hydrogen is $1{\text{s}}^1$. It resembles the alkali metals (group 1A); it can be oxidized to the ${\text{H}}^{+}$ ion.

Hydrogen resembles the halogens (group 7A) in that it forms hydride ${\text{H}}^{-}$, which is isoelectronic to helium $1{\text{s}}^2$.

Dihydrogen undergoes with a number of elements in order to form binary compounds called hydrides.

Hydrides are classified into three types, that are ionic hydrides, covalent hydride, and interstitial hydrides
