Zinc is an electron donor. It typically donates electrons in chemical reactions to form stable compounds.
The ground state electron configuration for zinc is [Ar] 3d10 4s2. In this configuration, zinc has a completely filled 3d subshell and a filled 4s subshell.
The valence shell of sodium has one electron.

In the electron dot diagram for a sulfur ion, there would be eight dots represented. This is because sulfur typically forms an ion with a 2- charge, so it needs two more electrons to achieve a full outer shell of eight electrons.
