Interstitial hydrides are formed when hydrogen reacts with transition metals and occupies the interstitial spaces in the metal lattice. Ex: Palladium absorbs

Hydrogen and forms Palladium hydride.

Additionally,
Ionic hydrides are formed when hydrogen reacts with highly electropositive s-block elements except \mathrm{Be} and \mathrm{Mg}. \mathrm{BeH}_2$ \& $\mathrm{MgH}_2 have covalent character.

Covalent hydrides are compounds of hydrogen and non-metals due to their similarity in electronegativity. As non-metals are present in p−block, hence p−block elements form covalent hydrides.
