S2-
A sulfur atom becomes a sulfur ion by losing or gaining electrons. If a sulfur atom loses electrons, it becomes a positively charged sulfur ion (sulfur cation). If it gains electrons, it becomes a negatively charged sulfur ion (sulfur anion).
18 electrons
In a sulfur ion with a charge of 2-, there are 18 electrons (16 from the neutral sulfur atom and two additional electrons to account for the negative charge). The number of protons remains the same as in a neutral sulfur atom, which is 16.
The ion notation for sulfur with 18 electrons would be S2-. This means that sulfur has gained two extra electrons to achieve a full octet, giving it a -2 charge.
Sulfur ion has gained or lost electrons, making it positively or negatively charged. In a sulfur ion, the number of protons remains the same, but the number of electrons changes. This change in electrons leads to the ion having a different charge than a neutral sulfur atom.

Sulfur typically gains 2 electrons to form an ion with a -2 charge.

The correct name for this compound would be iron(III) sulfide. Iron (Fe) has an atomic number of 26, so it contains 26 electrons in its neutral state. When it forms a +3 ion by losing 3 electrons, it now has 23 electrons. Sulfur (S) typically forms a -2 ion by gaining 2 electrons, bringing the total to 24 electrons when combined with iron(III).
S2- ion is isoelectronic with argon (with 18 electrons).
they both gain 2 electrons becoming the anions Oxide and Sulfide, O2- and S2-
Sulfur can both gain and lose electrons when forming ions. It can gain two electrons to form a sulfide ion (S2-) or lose two electrons to form a sulfide ion (S2+).
A sulfur atom has 6 valence electrons, while a sulfide ion has 8 valence electrons because it gains two electrons to achieve a stable electron configuration.
