Gallium has a number of sulfides
Ga2S, [Ga+]2 S2- (gallium(I) sulfide)
GaS, [Ga24+] [S2-]2 gallium (II) sulfide
Ga4S5 - undocumented structure so simply call it tetragallium pentasulfide
Ga2S3, [Ga3+]2 [S2-]3 gallium(III) sulfide
These compounds all have a large degree of covalent character in their bonding so expressing them as ionic substances is only a useful formalism to understand the oxidation states of the metal.
Ga2(SO3)3, chemical compound composed of 2 gallium, 3 sulfur, and 9 oxygen
Ga2(SO3)3
Ga(SO3)
K2S is the formula for the ionic compound formed from potassium and sulfur.
K2S is the formula for the ionic compound formed from potassium and sulfur.
Ionic gallium takes a 3+ (Ga3+) charge, and the hydroxide ion takes a 1- (OH-) charge. Therefore, the chemical formula (the combination of the ions to form an ionic compound) is Ga(OH)3, which satisfies all the charges. There are several other forms of ionic gallium compounds as well, include Gallium Oxide (Ga2O3) and Gallium Oxide Hydroxide (GaOOH).
Gallium (Ga) is a chemical element, a metal.
The reaction of chlorine and sulfur can give a few different products, each of which is considered to have covalent rather than ionic bonding.
gallium (III) carbonate - Ga2(CO3)3 gallium (III) oxide - Ga2O3

Rb2S====
Gallium arsenide, but it's more covalent than ionic- its a semiconductor
Molecular
Sodium and sulfur together in a compound represents a ionic bonds, because sodium is a metal and sulfur is a non-metal. The chemical formula for this compound would Na2S, and its name would be sodium sulfide.
Ionic gallium takes a 3+ (Ga3+) charge, and the hydroxide ion takes a 1- (OH-) charge.

The formula unit for the ionic compound made of strontium and sulfur is SrS, called strontium sulfide.
