Question

Which metal forms a stable hydride

Answer 1

The only two exceptions are beryllium hydride and magnesium hydride. Due to the negatively charged ion (H-) they are also known as Ionic Hydride. They have high density since these are stable molecules.


Hope it help u.

Answer 2

NH3 is the most stable hydride among the hydrides of group 15 elements because the strength of E-H (Here E = N, P, As, Sb, or Br) bond decreases down the group due to increase in size of the central atom.

beryllium hydride and magnesium hydride.
