Non-stoichiometric compounds of transition elements are called___________________?
Correct answer: D. interstitial compounds
- A. hydrates
- B. hydrides
- C. binary compounds
- D. interstitial compounds
Explanation
Non-stoichiometric compounds have compositions that do not follow simple whole-number ratios because small atoms such as hydrogen, carbon or nitrogen occupy holes in a metal lattice. These are called interstitial compounds. The likely mistake is choosing hydrides, but hydrides are only compounds specifically containing hydrogen with another element.

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.
