Hydrogen reacts with different elements to from variety of hydrides. Group 1 and 2 elements form white crystalline, ionic hydrides.Their stability depends upon ionic character and lattice energy. Convalent hydrides are most common type of hydrides. Transition metals form interstitial hydrides. The co-ordination number of Na in solid NaH is :
