Vedclass · Answer

(D) By $Z = 3$,we mean that the atomic number of the element is $3$.Its electronic configuration is $2, 1$.Since the outermost shell has only $1$ electron,the element needs to lose $1$ electron to achieve a stable configuration.Therefore,the valency of the element is $1$.The element with atomic number $Z = 3$ is lithium.

If $Z = 3$,what would be the valency of the element? Also,name the element.
