No, sulfur accepts two electrons forming sulphide ion.
It becomes a sulfur ion with a charge of -2.
The ion S(2-) has 16 protons and 18 electrons.
S2- ion is isoelectronic with argon (with 18 electrons).
The symbol is S2- because to become an ion a sulfur atom gains two electrons and each electron has a 1- charge.
8 because sulfur has 6 valence electrons and when it becomes sulfide it gains two electrons making it 6+2=8.
