All atoms except hydrogen can also contain one or more neutrons in the nucleus. Negatively charged electrons orbit the nucleus. The number of protons defines an element (hydrogen has one proton, helium has two, and so on) of the atom. Nuclei with the same number of protons but different numbers of neutrons are different isotopes of the same element.

Almost all elements on the periodic table have at least two different natural isotopes. Many elements have synthetic isotopic forms that have been made by nuclear chemists and/or physicists. Chemically, isotopes appear to be the same. For example, the two most abundant forms of uranium look physically the same and react to other materials in a similar manner.
