 (no͞o′klīd′, nyo͞o′-)
A type of atom specified by its atomic number, atomic mass, and energy state, such as carbon-14.

nu·clid′ic (no͞o-klĭd′ĭk, nyo͞o-) adj.


(General Physics) a species of atom characterized by its atomic number and its mass number. See also isotope
[C20: from nucleo- + -ide, from Greek eidos shape]


(ˈnu klaɪd, ˈnyu-)

1. an atomic species in which the atoms have the same atomic number and mass number.
2. an individual atom in such a species.
[1947; nucl(eus) + -ide < Greek eîdos shape]
