Question

Why interstitial hydrides have a lower density than the parent metal?​

Answer 1

Answer:

The empty spaces between the molecules of the pure metal are the spaces where a molecule of relatively small radius can be filled. So,density is always increased in interstitial compounds not decreased when compared with its parent pure metal.

Answer 2

Answer:

1. d block elements form metallic or interstitial hydrides, on heating with dihydrogen under pressure.

2. Hydrogen atom being small in size occupy some in the metallic lattice producing distortion without any change in its type.

3. The densities of these hydrides are lower than those of metals from which they are formed since the crystal lattice expands due to the inclusion of dihydrogen.
