MCQ

In all its properties, hydrogen resembles :

A
alkali metals only
B
halogens only
✓
both alkali metals and halogens
D
neither alkali metals nor halogens

✓

Answer

Correct option: C.

both alkali metals and halogens

Hydrogen resembles alkali metals and halogens in all its properties. The electronic configuration of hydrogen, alkali metals and halogens are $1 s^1, \mathrm{~ns}^1$ and $ n s^2, n p^3$ respectively. All are short by one electron from noble gas configuration. Hence, all have similar chemical properties.
