Question

Comprehension: d-block elements form complexes owing to available low-energy vacant orbitals and show varied properties (catalytic, magnetic, alloy and interstitial-compound formation). Interstitial compounds form when small atoms such as carbon or boron occupy the interstices of a d-block metal lattice; no chemical bonds are made, so chemical properties stay nearly the same while physical properties can change. Which physical property of an interstitial compound remains essentially the same as that of the parent metal?

Accepted Answer

Electrical conductance. Interstitial compounds keep metallic electrical (and thermal) conductivity like the parent metal, whereas hardness increases and malleability/ductility decrease.
