(A) The electronic configuration of iron $(Fe)$ is $[Ar] \, 3d^6 4s^2$.When iron loses two electrons,it forms the ferrous ion $(Fe^{2+})$ with the configuration $[Ar] \, 3d^6$.When iron loses three electrons,it forms the ferric ion $(Fe^{3+})$ with the configuration $[Ar] \, 3d^5$.Therefore,the net charge on a ferrous ion is $+2$.
