That's a good start! Here's a more precise way to think about molecules:

Molecules are formed when two or more atoms bond together chemically.

Here's why that's important:

* Elements vs. Molecules: Elements are the basic building blocks of matter (like carbon, oxygen, hydrogen). Molecules are formed when these elements chemically combine.

* Types of Bonds: Atoms bond together through various forces, most commonly covalent bonds where they share electrons.

* Examples:

* Water (H₂O): Two hydrogen atoms and one oxygen atom bond to form a water molecule.

* Carbon Dioxide (CO₂): One carbon atom and two oxygen atoms bond to form a carbon dioxide molecule.

* Glucose (C₆H₁₂O₆): Six carbon atoms, twelve hydrogen atoms, and six oxygen atoms bond to form a glucose molecule.
