Vedclass · Answer

(A) Hydrogen $(H)$ has an electronic configuration of $1s^1$. By gaining one electron,it achieves the $1s^2$ configuration,which is the stable electronic configuration of the noble gas helium $(He)$. Similarly,halogens (Group $17$ elements) have an $ns^2 np^5$ configuration and tend to gain one electron to achieve the stable $ns^2 np^6$ configuration of the nearest noble gas. Therefore,in this specific respect,hydrogen resembles halogens.

Hydrogen has a tendency to gain one electron to acquire the helium configuration. In this respect,it resembles:
