What is interstitial hybrides

1.	What is interstitial hybrides
Answer» Thanks all of u<br>Gaurav can you explain the concept of non stoichiometery here.<br>‘Non-stoichiometric’ are those hydrides in which the ratio of the metal to hydrogen is fractional. This fractional ratio is not fixed but varies with temperature and pressure. Many of the d-block elements and f-block elements (lanthanoids and actinoids) react with hydrogen at elevated temperature to give metallic or non-stoichiometric hydrides. For example LaH2.87, TiH1.8.,Zr H1.9, VH1.6\xa0etc. Since in these hydrides, hydrogen is present in the interstices (holes or voids) existing in between the atoms, therefore these hydrides are also called interstitial hydrides.<br>It is really very easy trust me interstial hydrides are formed by d and f block elements.in d block group 3,4,5,10,11,12forms these hydrides .group 6,7,8,9 is called hydride gap.these are called interstial as hydrogen atom may occupy may occupy interstial sites in these lattices .hope this helped you.
