well first off S-2 is a monoatomic anion
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-
Ammonium sulfide is soluble in water.
It is called the Sulphide ion
S^2- is not polyatomicPO4^3- is polyatomicHCl in not an ionN2 is not an ion
The cation in lithium sulfide is Li+, which is the lithium ion. The anion in lithium sulfide is S2-, which is the sulfide ion.
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.
The chemical formula for the sulfide ion is S2-. To write the sulfide ion in a compound, you would typically pair it with a cation (positively charged ion) to form an ionic compound, such as sodium sulfide (Na2S) or iron(II) sulfide (FeS).
It has a charge of 2-, S2-
Ammonium sulfide is soluble in water.
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-.
It is called the Sulphide ion
