The ratio of Cu ions (Cu2+) to sulfide ions (S2-) in copper sulfide (Cu2S) is 1:1, meaning for every Cu2+ ion there is one S2- ion. This results in a 1:1 ratio of Cu2+ to S2-.

The cation S2- is called sulfide ion. It has a charge of -2 and is formed when sulfur gains two electrons to achieve a stable electron configuration.
It has a charge of 2-, S2-
S2-
The positive ion for CaS is Ca^2+ (calcium ion) and the negative ion is S^2- (sulfide ion).
The chemical name for S2- is sulfide ion.
The symbol for sulfide, one of the many ions, is S2-.
The negative ion of lithium sulfide is sulfide ion (S2-). This is formed when lithium sulfide (Li2S) dissociates into its ions in solution.
18 electrons
The ion is S2-.
S2-
No. S2- is a monatomic ion. A polyatomic ion contains at least two atoms. You can identify a polyatomic ion as it will have the symbols for more than one element (OH-), a subscripted number (O22-), or a combination of the two (CO32-). The superscript in the ion only indicates the charge.
