What is Atom and Molecule? Atoms and molecules are an important part of science and the building blocks of matter. Understanding them is the foundation for understanding all branches of science.

For example, we've got water. Water is a compound of hydrogen and oxygen. The chemical name for water is H₂O because each of its molecules contain two hydrogen atoms and one oxygen atom.
