Isotopes are a type of atom, the smallest unit of matter that retains all the chemical properties of an element. Atoms with the same number of protons but different numbers of neutrons are called isotopes. Read our explainer to find out how isotopes can help experts understand more about water resources, atmospheric pollution, and the geographical and botanical provenance of food. Unstable isotopes, which emit radiation, also known as radioisotopes, can be used in medicine, industry, agriculture and industrial applications.
