• A. ionic, interstitial, electron rich
• B. electron rich, ionic, interstitial
• C. ionic, electron rich, interstitial
• D. electron rich, interstitial, ionic

Hint:

Hydrides: \[ \text{Alkali metals} \rightarrow \text{Ionic} \] \[ \text{Transition metals} \rightarrow \text{Interstitial} \] \[ \text{Group 15 hydrides} \rightarrow \text{Electron rich} \]

Answer 1

The Correct Option is B
