The number of electrons in a neutral Sulphur atom is 16
To become the sulphide ion it needs to gain two electrons to form the Argon electron configuration.
Hence the sulphide ion will have 18 electrons (S^2-).
Do not confuse the '2' two mean two atoms of sulphur. It does not - it means one sulphur atom has gained '2' electrons.

Yes. A sulphur atom has 16 electrons. A negative 2 charge would indicate an increase of 2 electrons.

A neutral sulfur atom has 16 electrons. Neutral sulfide (S2) has 32. Since the charge on sulfide is -2, sulfide has 34 electrons.

yes it is 18
reason, since the atomic number for sulphur is 16, that means it has 16 protons and 16 electrons, but since we interested only in the number of electrons it is (16) this is in an atom of sulphur, sulphide ion means that sulphur atom gained 2 electrons, as a result the toal number of electrons is = 16 + 2 = 18 e
