Hydride gap corresponds to elements of
- A group 7, 8, 9
- B group 13
- C group 15, 16, 17
- D group 14
Answer & Solution
Correct Answer
(A) group 7, 8, 9
Step-by-step Solution
Detailed explanation
There is a hydride gap where elements do not form hydrides. These metals have low affinity for hydrogen in their normal oxidation state. Therefore, metals of group 7,8 and 9 in periodic table do not form hydride. \(\therefore\) Group 7,8 and 9 referred as hydride gap.
