It is called the Sulphide ion
Mercury(II) Sulfide. Made of Mercury cation and Sulfide anion.
If the name of the acid ends in the letters "ic" and the acid contains oxygen, the name of the anion formed from it replaces the "ic" with "ate". If the name of the acid ends in the letters "ous" and the acid contains oxygen, the name of the anion formed from it replaces the "ous" with "ite." If the name of acid ends in the letters "ic" and the acid does not contain oxygen, the name of the anion formed by the acid changes "ic" to "ide", and if the name of the acid begin with "hydro", these letters are deleted from the name of the anion.
The ClO3- anion formed when HClO3 is dissolved is called Chlorate
The name "s2" is typically used as a placeholder or variable name in programming and mathematics. It does not have a specific or standard name beyond this usage.
The sulfide anion is S2-
A typical monatomic anion will have the suffix -ide; Examples: oxide (O2-), chloride (Cl-), sulfide (S2-).
It is called the Sulphide ion
Assuming I've understood what you're asking: -ide (as in, chlorine becomes chloride to indicate that it's an anion).
The cation in lithium sulfide is Li+, which is the lithium ion. The anion in lithium sulfide is S2-, which is the sulfide ion.
Sodium sulfide is Na2S. Two ions can be separated: Na+ and S=. The negative ion S= is the anion.
The negative ion of lithium sulfide is sulfide ion (S2-). This is formed when lithium sulfide (Li2S) dissociates into its ions in solution.
The chemical name for S2- is sulfide ion.
Mercury(II) Sulfide. Made of Mercury cation and Sulfide anion.
The chemical formula of sodium sulfideis Na2S. The sodium cation is Na+ and the sulfide anion is S2-.
It is called chloride ion.
This is a polyatomic anion.
