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.
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+
The positive ion for CaS is Ca^2+ (calcium ion) and the negative ion is S^2- (sulfide ion).
Sulfide is divalent ion. it is S2-
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.
S(2-) : sulfide ion Al(3+) : aluminum ion
+6, because the oxidation number of oxygen is -2x3=-6
0 o ll ll -o-s-0-s-o- l l o--0-0 hope it works.......................
No, oxide is just an oxygen ion. The formula is just O(-2 charge), hence not a polyatomic ion. Hydoxide on the other hand is a polyatomic ion, formula being OH(-1 charge)
