An organic molecule is found in living systems. They are typically composed of carbon atoms in long chains or rings that are attached to other atoms. These other atoms often include elements such as oxygen, hydrogen, and nitrogen. Organic molecules are composed of two or more elements and are produced by or found in living organisms.
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.
