S-3
The ion is S2-.
It is called the Sulphide ion
The chemical formula of calcium sulfide is CaS; the ions are Ca2+ and S2-.
The symbol for sulfide, one of the many ions, is S2-.
Ca is the periodic symbol for Calcium. S is the periodic symbol for Sulfur. As such, CaS2 is a compound of calcium and sulfur.
The negative ion of lithium sulfide is sulfide ion (S2-). This is formed when lithium sulfide (Li2S) dissociates into its ions in solution.
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 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).
Yes, ammonium sulfide is an ionic compound. It is composed of the ammonium ion (NH4+) and the sulfide ion (S2-), which are held together by ionic bonds formed through the transfer of electrons from the ammonium ion to the sulfide ion.
The chemical formula for the hydrogen sulfide ion is (HS^-).
The symbol for hydrogen sulfide is H2S.
S(2-) : sulfide ion Al(3+) : aluminum ion
