Question

What are binary compound of hydrogen? Describe briefly the hydrides formed by alkail metals and Halogens. ​

Answer 1

In this group, the hydrogen acts as the hydride ion (\(H^-\)). They bond with more electropositive metal atoms. Ionic hydrides are usually binary compounds (i.e., only two elements in the compound) and are also insoluble in solutions. Ionic hydrides combine vigorously with water to produce hydrogen gas.
