Answer: the atomic number and the mass number
Which numbers are shown in the symbol for a radioactive nuclide?

91 rows · The mass of the nuclide (in daltons) is A (m n − E / k) where E is the energy m n is 1.008664915 Da and k = 931.4941 the conversion factor between MeV and daltons. half-life column The main column shows times in seconds (31 556 926 seconds = 1 tropical year ) a second column showing half-life in more usual units (year day) is also provided.

A table or chart of nuclides is a two-dimensional graph of isotopes of the elements in which one axis represents the number of neutrons (symbol N) and the other represents the number of protons (atomic number symbol Z) in the atomic nucleus. Each point plotted on the graph thus represents a nuclide of a known or hypothetical chemical element. This system of ordering nuclides can offer a greater insight into the characteristics of isotopes than the better-known periodic table which shows only elements and not …

On Earth naturally occurring radionuclides fall into three categories: primordial radionuclides secondary radionuclides and cosmogenic radionuclides. • Radionuclides are produced in stellar nucleosynthesis and supernova explosions along with stable nuclides. Most decay quickly but can still be observed astronomically and can play a part in understanding astronomic processes. Primordial radionuclides such as uranium and thorium exist in th…

A nuclide is 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 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…
