The Reason of Interstitial Hydrides…

The Reason of Interstitial Hydrides –
(i) As the size of central atom increases, electronegativity decreases, thus repulsion of bond pair and lone pair of central atom decreases.
(ii) As the size of central atom increase, electron density decreases.
(iii) As the stability of hydrides decreases, the reducing character increases.
(iv) They are volatile or non-volatile. These interstitial hydrides are either gases or liquids.
