s2-
Sulfur ion with a -2 charge is called sulfide ion (S^2-).
S(2-) : sulfide ion Al(3+) : aluminum ion
The sulphide (or sulfide) ion is similar to a sulfur atom except for 2 additional electrons, so its formula is S2-. In older references you might find this formula written S-2 or S--.
The most common ion formed by sulfur is the sulfide ion (S2-).
None the formation of an ion has nothing to do with losing or winning atoms.

This should be SO4-2 ion. sulfur shows +6 in this ion.
In the thiosulfate ion (S₂O₃²⁻), the oxidation state of sulfur (S) can be determined by considering the overall charge and the oxidation states of oxygen. Oxygen typically has an oxidation state of -2. In S₂O₃²⁻, there are three oxygen atoms contributing a total of -6. To balance the -2 charge of the ion, the total oxidation state of the two sulfur atoms must be +4. Therefore, the average oxidation state of sulfur in S₂O₃²⁻ is +2, but one sulfur is usually assigned an oxidation state of +6 and the other -2.
Sulfur ion with a -2 charge is called sulfide ion (S^2-).
The common simple ion is S-2 and the most common polyatomic ion is probably SO4-2.
O = 2- Al = 3+ N = 3- I = 1- Mg = 2+ Ba = 2+ S = 2- K = 1+
Sulfide is divalent ion. it is S2-
The positive ion for CaS is Ca^2+ (calcium ion) and the negative ion is S^2- (sulfide ion).
The element that forms an ion with an electronic configuration of Ar with a -2 charge is oxygen (O). When oxygen gains two electrons, it achieves a stable electron configuration similar to argon.

+6, because the oxidation number of oxygen is -2x3=-6
The correct name for Cu₂S₂O₃ is copper(I) thiosulfate. In this compound, copper has a +1 oxidation state, and the thiosulfate ion (S₂O₃) has a -2 charge. This naming reflects the composition and oxidation states of the elements involved.
