In A Nutshell. Atoms are the smallest pieces of matter; they are made of particles (protons and electrons). When atoms are grouped together, these groups are called molecules (the smallest pieces of compounds). You probably think of atoms, molecules, and particles as all being extremely small pieces of matter.
Atoms have the  same number of protons and electrons, â¦ because otherwise, you would  have an ion.   A molecule consists of two or more atoms bonded together.    Atoms are single units of elements.   Molecules are agglomerations of two or more atoms  (of the same or different elements). A molecule is the smallest  particle of a chemical compound. Molecules are formed by atoms in a  multitude of different arrangements.   - Most atmospheric oxygen forms diatomic molecules (O2),  but also ozone (O3)   - One molecule of water has one atom of hydrogen and two atoms of  oxygen. So-called heavy water contains deuterium, which is hydrogen  that has neutrons.
