Vedclass · Answer

(B) The given electronic configuration $1s^2, 2s^2 2p^6, 3s^1$ corresponds to the element $Sodium$ ($Na$,$Z = 11$).Since the valence shell has $1$ electron $(3s^1)$,the metal $M$ exhibits a valency of $+1$.Oxygen $(O)$ typically exhibits a valency of $-2$.To form a neutral oxide,two atoms of $M$ ($+1$ charge each) combine with one atom of $O$ ($-2$ charge).Therefore,the formula of the oxide is $M_2O$.

The electronic configuration of a metal $M$ is $1s^2, 2s^2 2p^6, 3s^1$. The formula of its oxide will be
