what forms when two atoms combine?

When two atoms combine chemically, they form a molecule.

Basic idea

• A molecule is what you get when two or more atoms join together by chemical bonds.

• Those atoms can be the same element (like two oxygen atoms forming O₂) or different elements (like hydrogen and oxygen forming H₂O).

Quick chemistry scoop

• Atoms stick together because sharing or transferring electrons makes them more stable, and this “sticking together” is called a chemical bond.

• The bonded group of atoms is called a molecule; if the atoms are from different elements, that molecule is also a compound (for example, water is a molecular compound).
