SUMMARY
Ionic hydrides exhibit greater density than their corresponding metals due to the formation of low-radius ions from Group I and II metals. These metals, when forming ionic compounds, lose their valence electrons, resulting in smaller ionic radii. Additionally, the inclusion of H- ions, which also possess a low radius, contributes to the overall density of ionic hydrides. This phenomenon contrasts with interstitial hydrides, which have lower densities due to the expansion of the crystal lattice from hydrogen inclusion.
