Ionic hydrides are formed by

Assertion : Saline hydrides are ionic in nature. Reason : Saline hydrides are formed by the elements having high electronegativity values.

Group-II elements react with water evolving hydrogen. This reactivity increases down the group from Be to Ba. They displace hydrogen from acids except Be with oxygen Be, Mg and Ca form monoxides while Sr, Ba and Ra form peroxides on heating with hydrogen, they form metal hydrides except Be with carbon, they form carbides on heating such as acetylides, methanides and allylides. When heated with halogens they form halides having different properties. Ionic hydride is not formed by

The densities of ionic hydrides are greater than that of the metal from which they are formed- why ?
