Question:
In long form of periodic table, the d-block element which forms interstitial hydride is
In long form of periodic table, the d-block element which forms interstitial hydride is
Show Hint
Interstitial hydrides are common for early transition metals with small atomic radii.
Look for d-block elements in periods 4 and 5.

The Correct Option is D
Solution and Explanation
Interstitial hydrides are formed by transition metals, especially those from the d-block, where small hydrogen atoms occupy the voids (interstices) in the metal lattice. These are generally formed by metals like Ti, V, Cr, etc.
Chromium (Cr), being a first-row transition metal, has the right atomic size and lattice structure to allow hydrogen atoms to occupy interstitial positions and form interstitial hydrides.
