Nuclide
Updates to Article Attributes
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 and will additionally have a specific energy state of of its nucleus.
Radionuclides are unstable nuclides that undergo radioactive decay.
Types of nuclides are demonstrated below:
isotopes:
samesame atomic number (Z)isotones:
samesame neutron number (N)isobars:
samesame mass number (A)isomers:
samesame atomic (Z) and mass (A)numbersnumbers, different energy states
History and etymology
Truman Kohman, a 20th-century20th century American chemist, proposed proposed the use of 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.
