$\begingroup$ But in S block, BeH2 is a covalent compound and in P block, I think GaH3 is an ionic compound. So BeH2 & GaH3 will be Saline/Saltlike or Molecular Hydrides? $\endgroup$

$\begingroup$ @NipunKulshreshtha I was about to update on BeH2. I will update the answer. But GaH3 is unfortunately covalent. It has been detected as a transient species in the gas phase at very low temperature. However, it is stable in its dimeric form of formula $\ce{H2Ga(H2)GaH2}$ which points towards its covalency and polymerism. $\endgroup$

$\begingroup$ @NilayGhosh aww come on, what is so unfortunate about gallium hydride being covalent? $\endgroup$

$\begingroup$ @OscarLanzi OP assumed gallium hydride was ionic/salt like :) $\endgroup$
