What type of compound is composed of two or more kinds of atoms?

Monomers
Polymers
Isomers
Molecules

The correct answer is: Molecules

A monomer is a single unit that can combine with other units to form a polymer, but it is not composed of multiple types of atoms itself. A polymer is a large molecule composed of many repeating units, but these units are not necessarily different types of atoms. Isomers are compounds with the same molecular formula but different structures, so they are not necessarily composed of different kinds of atoms. A molecule, on the other hand, is the smallest unit of a compound and can be composed of two or more different types of atoms. It is the only option that accurately describes a compound composed of different kinds of atoms.
