Which term means a group of atoms bonded together?

• A. Compound
• B. Element
• C. Molecule
• D. Mixture

Answer: (C)

A molecule is a group of atoms bonded together. When atoms join by chemical bonds, they form a unit that has its own properties, and that unit is a molecule. A molecule can be as simple as two hydrogen atoms (H2) or as complex as many atoms in a larger structure. A compound is specifically a molecule that contains more than one type of element, so while all compounds are molecules, not all molecules are compounds. An element is pure substance made of only one kind of atom, not a bonded group of different atoms. A mixture is a combination of substances that are not chemically bonded.
