Lewis Dot Structure Question?

Question

what would it be for S+ and a seperate question is what would it be for MG2+

one par of electron, two lone electrons

two pairs of electrons, two lone electrons

three pairs of electrons

Two pairs of electrons, one lone electron

two pairs of electrons, three lone electrons

three pairs of electrons, one lone electron

one pair of electrons, 3 lone electrons

Two pairs of electrons

one pair of electrons, two lone electrons

one pair of electrons

four pairs of electrons

two magnesium atoms bound by 2 bonds

Answer 1

The S+ cation would have one pair of electrons and 3 lone electrons.

For Mg 2+? It would have no valence electrons in the 3rd shell. You could show it as just Mg with no electrons around it, or since it has a full second shell (technically now your valence shell), you could show it with four pairs of electrons.
