Which is the net charge on ferrous ion ?

$$\begin{gathered} { }_{26}\mathrm{Fe} \stackrel{ }{\to } \left[\mathrm{Ar}\right]3{\mathrm{d}}^6 4{\mathrm{S}}^2 \\ \mathrm{F}{\mathrm{e}}^{++}\stackrel{ }{\to } \left[\mathrm{Ar}\right]3{\mathrm{d}}^6 4{\mathrm{S}}^0 \\ \mathrm{F}{\mathrm{e}}^{+++}\stackrel{ }{\to } \left[\mathrm{Ar}\right]3{\mathrm{d}}^5 4{\mathrm{S}}^0 \end{gathered}$$

In +2 state Fe is called ferrous and in +3 state as ferric.
