Question

What are interstitial compounds? Why are such compounds well known for transition metals?

Answer 1

Hey !!

Interstitial compounds are those in which small atoms occupy the interstitial sites in the crystal lattice. Interstitial compounds are well known for transition metals because small-sized atoms of H , B , C , N, etc can easily occupy position in the voids present in the crystal lattices of transition metals.

Hope it helps you !!

Answer 2

Answer:

Transition metals are large in size and they also contain lots of interstitial sites.

These interstitial sites can be used to trap atoms of other elements (that have small atomic size), such as H, C, N. The compounds resulting are called interstitial compounds.
