Question

Resemblance with halogens.

Answer 1

1. Electronic configuration – Like halogens, H has one electron less than the nearest inert gas. 

2. Electronegative character H can gain 1 e^- to form hydride

H + e^- → H^- 

3. Oxidation state – H shows – 1 oxidation state Na⁺ H^- .

4. Liberation at anode – When fused alkali metal hydrides are subjected to electrolysis, hydrogen is liberated at anode.
