A Sulfide ion has a full complement of 8 valence electrons.
Sulfur is element 16. It has 6 valence electrons in its outer energy level, however, sufide is S2- so it has gained 2 electrons to fill its outer energy level.
The answer is 16 electrons.
The sulfur atom has 16 electrons and 6 valence electrons. To reach eight electrons, it gains two, reaching a total of 18.
There are 18 electrons in a sulfide ion.
16 protons and 18 electrons
S2- has 18 electrons

they both gain 2 electrons becoming the anions Oxide and Sulfide, O2- and S2-
The sulfur atoms gain two electrons to form the sulfide ion.
Protons = 16 Electrons = 18
8 because sulfur has 6 valence electrons and when it becomes sulfide it gains two electrons making it 6+2=8.
Gained 2 electrons.
A sulfur atom gains 2 electrons when it becomes a sulfide ion.

Sulpher gains two electrons as it is in group 6 and to be stable it would obviously need two more electrons.. :)

Gained 2 electrons.
it has 2 more electrons than protons.
The nuclear charge is the same for both species, but the eight valence electrons in the sulfide ion experience a greater amount of electron-electron repulsion than do the six valence electrons in the neutral sulfur atom. This extra repulsion in the sulfide ion increases the average distance between the valence electrons, so the electron cloud around the sulfide ion has the greater radius.
The number of protons of an element does not change when it undergoes a chemical change. It is the number of electrons that changes. Sulfur has 16 protons, and so does the sulfide ion. However, sulfur has 16 electrons, while the sulfide ion (S2-) has 18 electrons.
