A nuclide is a nuclear-centric term describing an atomic species by its nuclear composition and nuclear energy state. A nuclide has a specific number of protons and neutrons and will have a specific energy state in its nucleus. Radionuclides are unstable nuclides that undergo radioactive decay.
Types of nuclides are demonstrated below:
isotopes: same atomic number (Z)
isotones: same neutron number (N)
isobars: same mass number (A)
isomers: same atomic (Z) and mass (A) numbers, different energy states
History and etymology
Truman Kohman, a 20th-century American chemist, proposed using the term nuclide in 1947 (and its derivative radionuclide) as a more accurate substitute for the terms isotope and radioisotope. This recommendation was not widely adopted in scientific literature until the 1960s.
