Vedclass · Answer

(C) Hydrogen exhibits properties similar to both alkali metals and halogens.$1$. Like alkali metals $(ns^1)$,hydrogen has one electron in its valence shell $(1s^1)$ and can lose it to form $H^+$.$2$. Like halogens $(ns^2 np^5)$,hydrogen is one electron short of the nearest noble gas configuration and can gain one electron to form $H^-$.Therefore,hydrogen shows resemblance to both groups.
