Sodium sulfide is Na2S. Two ions can be separated: Na+ and S=. The negative ion S= is the anion.
The compound formed from sodium and sulfur is sodium sulfide (Na2S).
The ionic compound formed by sodium (Na) and sulfur (S) is sodium sulfide with the chemical formula Na2S.
The name of an ionic compound typically consists of the cation followed by the anion. For example, in the compound sodium chloride (NaCl), "sodium" is the cation and "chloride" is the anion.
Sodium bromide is an ionic compound because it is composed of a metal cation (sodium) and a nonmetal anion (bromide) held together by ionic bonds.
A binary ionic compound is formed between two elements, typically a metal cation and a nonmetal anion. For example, sodium chloride (NaCl) is a type of binary ionic compound where sodium (metal) forms a cation and chlorine (nonmetal) forms an anion.
The chemical formula of sodium sulfideis Na2S. The sodium cation is Na+ and the sulfide anion is S2-.
The compound formed from sodium and sulfur is sodium sulfide (Na2S).
The ionic compound formed by sodium (Na) and sulfur (S) is sodium sulfide with the chemical formula Na2S.
It is an ionic compound, so its name is sodium sulfide. Greek prefixes are not used when naming an ionic compound.

Sodium bromide is an ionic compound because it is composed of a metal cation (sodium) and a nonmetal anion (bromide) held together by ionic bonds.
A binary ionic compound is formed between two elements, typically a metal cation and a nonmetal anion. For example, sodium chloride (NaCl) is a type of binary ionic compound where sodium (metal) forms a cation and chlorine (nonmetal) forms an anion.
The formula of the anion in sodium bromide is Br^-. Sodium bromide is composed of the sodium cation (Na^+) and the bromide anion (Br^-), which combine in a 1:1 ratio to form the compound NaBr.
Many metals form ionic sulfides containing the S2- ion, , for example sodium, Na2S sodium sulfide. Iron forms a sulfide, FeS, iron(II) sulfide and a disulfide, containing the S22- ion, iron, iron(II) disulfide, FeS2 , "fools gold"
The formula of sodium sulfide is Na2S, where the 2 should be a subscript. It means that in the ionic compound there are 2 moles of sodium ions for every 1 mole of sulfide ions.
Sodium hydride, NaH is ionic and contains Na+ and H-
Stannic sulfide (SnS2) is an ionic compound. It is composed of a metal (tin, Sn) and a nonmetal (sulfur, S), which typically form ionic bonds. Tin forms a 4+ cation while sulfur forms a 2- anion, resulting in the formation of an ionic compound.
