Asked in Premeth Test 11 — S and P Block, D Block and Chemical Bonding (13 March 2025) 2025

What are interstitial compounds?

Correct answer: A. Transition elements containing small proportion of H, B, C, N

  • A. Transition elements containing small proportion of H, B, C, N
  • B. Transition elements containing small proportion of He, Ne, Ar, Xe
  • C. The compounds in which transition elements are in their highest oxidation state.
  • D. The compounds of transition elements which are not stable.

Explanation

An interstitial compound, or interstitial alloy, is a compound that is formed when an atom with a small enough radius sits in an interstitial "hole" in a metal lattice. Examples of small atoms are hydrogen, boron, carbon and nitrogen.

About Electronic Structure of d-Block Elements

The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
