nuclide
Sign in to saveNuclides (or nucleides, from nucleus; also known as nuclear species) are a class of atoms characterized by their number of protons, Z, their number of neutrons, N, and their nuclear energy state.
AI overview
A nuclide is a specific type of atom defined by how many protons and neutrons it contains, along with how much energy its nucleus holds. Understanding nuclides matters because these differences determine what element an atom is and how stable or radioactive it will be.

Nuclides (or nucleides, from nucleus; also known as nuclear species) are a class of atoms characterized by their number of protons, Z, their number of neutrons, N, and their nuclear energy state.
The word nuclide was coined by the American nuclear physicist Truman P. Kohman in 1947. Kohman defined nuclide as a "species of atom characterized by the constitution of its nucleus" containing a certain number of neutrons and protons. The term thus originally focused on the nucleus.
