Ionic bond

[Banks]

So, I'm trying to draw a diagram for ionic bond, the question asks me to choose two atoms that could participate, and draw the valence shell

 

I chose Mg and S.

 

So, Mg has 12 protons and 12 electrons, and 2 valence electrons. S has 16 protons, 16 electrons and 6 valence electrons.

 

In the diagram, I drew two atoms with 3 shells, and I will draw an arrow pointing the electron transferring to S shell from Mg's outer shell.

 

How does that sound? Only one electron is transferred to S shell, is this correct? Or two? Because in Mg's outer shell there are 2 valence electrons...

 

Thanks guys.

Hint:The transfer of electron must be such that both atoms become stable.
