A model of a water molecule. The definition of a molecule is the smallest amount of something, particularly of a chemical substance, that can exist on its own. An example of a molecule are two atoms of hydrogen. molecule. molecule.
A molecule is a particle made up of two or more atoms that are chemically bonded together; the number of atomic nuclei making up a molecule is a determinate number. For example, HCl (g) is a molecule made of one hydrogen atom bonded to one chlorine atom. It is made of two atoms and is called a diatomic molecule. A crystal of NaCl (s) is not a molecule: it is an ionic lattice made up of an indeterminate number of atoms. Carbon dioxide is a molecule made of two oxygen atoms bonded to a carbon atom. It contains three atoms and is called a triatomic molecule. Silicon dioxide - best known as quartz - exists as an large covalent network made up of an indeterminate number of atoms.
