The building of all the profiles is correct; The total number of electrons is correct, as well as the filling of the shells to their entirety. However, some charge calculations are off. First, we see that sodium loses an electron in its structure. Hence, it acquires a charge of +1, not -1. Also, Fluorine gains 2 electrons in its 2p subshell. Thus, its charge is -2, not -1 and this is wrong too. The only correct answer is C; aluminum lose 3 electrons from its p-shell and hence it has a charge of +3.
