The sulfide ion is chemically notated as S2-.
Iron (|) Sulfide
To determine the formula for lithium sulfide using the crisscross method, you would write the symbols for lithium (Li) and sulfide (S) with their charges. The lithium ion has a charge of +1, while the sulfide ion has a charge of -2. By crisscrossing the charges, you get Li2S as the formula for lithium sulfide.
The formula for dissolved boric acid is H3BO3, and the formula for hydrogen sulfide gas is H2S.
Potassium sulfide
sodium and sulfide
Ferrous Sulfide is FeS
Iron (|) Sulfide

The skeleton equation for the reaction that produces iron II sulfide from iron and sulfur would be: iron + sulfur → iron II sulfide
The correct chemical formula for calcium sulfide is CaS. It consists of one calcium atom bonded to one sulfur atom.
Potassium sulfide
Diammonium sulfide
sodium and sulfide
Since it is an ionic compound, the overall charge should be zero. Iron (Fe) has possible different charges which are +2, and +3 however sulfide always has a charge of -2. Therefore, FeS is already balanced. When you write it, instead of writing "Iron Sulfide", you would write "Iron (II) Sulfide" this is because Iron has different charges and you must specify when you write it down.
