WebAug 19, 2024 · Incredible Isotopes. Like everything we see in the world, isotopes are a type of atom, the smallest unit of matter that retains all the chemical properties of an element. Isotopes are forms of a chemical element with specific properties. You can see the different chemical elements on the periodic table. (Graphic: A. Vargas/IAEA) WebM is the chemical symbol for the element. A is the mass number. Z is the atomic number. Stable isotopes: Isotopes that have stable nuclei and do not emit radiation.; Radioisotopes: Isotopes that have unstable nuclei and emit radiation.; For some elements, all isotopes are radioactive, such as uranium and radium.
