In the Nitrogen family the H - M - H bond angle in the hydrides MH3 gradually becomes closer to 90∘ on going from N to Sb. This shows that gradually:
The basic strength of hydrides increases
Almost pure p-orbitals are used for M - H bonding
The bond energies of M - H bond increase
The bond pairs of electrons become nearer to the central atom
