Two aluminum atoms and three sulfur atoms would have the formula Al2S3. When writing a formula for an ionic compound, the positive ion (in this case Al3+) is written first. Very often, an ionic compound is composed of a metal and a nonmetal, as in Al2S3, in which case the metal ion will be written first because it will always be positively charged.
Aluminum hydroxide is composed of aluminum, oxygen, and hydrogen atoms. The chemical formula for aluminum hydroxide is Al(OH)3, indicating that it consists of one aluminum atom, three oxygen atoms, and three hydrogen atoms.
Count them :- Al = 1 Cl = 3 that makes 4 atoms
Aluminum fluoride is made up of aluminum ions (Al3+) and fluoride ions (F−). The compound has a chemical formula AlF3, with each aluminum atom bonding to three fluoride atoms.

The number of sulfur atoms in a compound depends on the chemical formula of the compound. For example, in sulfur dioxide (SO2), there is one sulfur atom, while in sulfuric acid (H2SO4), there are one sulfur atom.
Aluminum sulfate is composed of aluminum, sulfur, and oxygen atoms. Its chemical formula is Al2(SO4)3, indicating that each molecule contains two aluminum atoms, three sulfate ions (each made of one sulfur and four oxygen atoms).
Al2S3
Aluminum hydroxide is composed of aluminum, oxygen, and hydrogen atoms. The chemical formula for aluminum hydroxide is Al(OH)3, indicating that it consists of one aluminum atom, three oxygen atoms, and three hydrogen atoms.
Aluminum is an element. It is made entirely of aluminum atoms.
Count them :- Al = 1 Cl = 3 that makes 4 atoms
Aluminum fluoride is made up of aluminum ions (Al3+) and fluoride ions (F−). The compound has a chemical formula AlF3, with each aluminum atom bonding to three fluoride atoms.
