Question

which block elements form interstitial compunds​

Answer 1

$\huge \pink {AnsWer}$

• A number of interstitial compounds are formed by the transition metals. Transition metals react with elements such as hydrogen, carbon, nitrogen, boron etc. to form interstitial compounds. As vacant spaces of the transition metals are filled up by small atoms, these compounds are hard and rigid.

Answer 2

Answer:

The compounds formed when small atoms of H, C or N get trapped inside the crystal lattice of metals is known as interstitial compounds. A number of interstitial compounds are formed by the transition metals. Transition metals react with elements such as hydrogen, carbon, nitrogen, boron etc. to form interstitial compounds.
