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) WebAn isotope is an alternative form of an element. Each isotope of an element has the same number of protons, but a different number of neutrons. The isotope is represented by the atomic symbol and mass number, such as He-4.
