What specific type of molecule consists of two or more different kinds of atoms bonded together?

The correct answer is based on the definition of a compound in chemistry. A compound is a type of molecule that is formed when two or more different kinds of atoms are chemically bonded together. This distinct characteristic sets compounds apart from simple molecules that consist of only one type of atom, such as those that make up elements.

For instance, water (H2O) is a compound made up of hydrogen and oxygen atoms. The combination of these different types of atoms creates a substance with unique properties that differ from those of the individual elements. This highlights the importance of the arrangement and types of atoms involved in forming compounds.

In contrast, a solution refers to a homogeneous mixture, not a specific type of bonded molecule. A molecule, in general, can be made of the same type of atoms or a combination of different types, but it doesn’t specifically denote two or more different atoms. An element consists of only one kind of atom, so it does not meet the criteria for having different types of atoms bonded together. Therefore, a compound is the most accurate term for a molecule made up of two or more different kinds of atoms.
