Solution:
Interstitial hydrides have a metallic bond. They are non stoichiometric which means the number of atoms of the elements presented cannot be represented by a ratio of small whole numbers and their composition varies with temperature and pressure $ZnH_{2}$ is an example of interstitial hydride while $NH_{3}, \, CH_{4} \, and \, H_{2}O$ are the examples of covalent hydride.
