Among lanthanoids europioum and ytterbium form ionic hydrides

Density of ionic hydrides is less while the density of interstitial hydrides is more than the metals from which they are formed

The rate of reaction of alkali metals towards hydrogen decreases from lithium to ceasium

Hydrogen gas can be purified by the phenomenon of Occlusion of hydrogen by palladium
