Nuclide

nuclide

(Science: physics) A species of atom characterised by the constitution of its nucleus, which is specified by the number of protons (Z), number of neutrons (N) and energy content or, alternatively, by the atomic number (Z), mass number (A = N _ Z) and atomic mass, to be regarded as a distinct nuclide, an atom must be capable of existing for a measurable time, thus, nuclear isomers are separate nuclides, whereas promptly decaying excited nuclear states and unstable intermediates in nuclear reactions are not.

Re: Molecular gene (genome) concept scientifically untenable

... you are misleading people by your comments of this kind; that too to support the erroneous molecular gene theory. Nuclear decay changes the nuclide. There are atomic species for an element; these species we distinguish as “nuclides”. For example P-31 with 15 protons and 16 neutrons is the ...
