History
The "Prout" is a unit of
nuclear binding energy, and is 1/12 the
binding energy of the
deuteron, or 185.5 keV. It is named after
William Prout. "Proutons" was an early candidate for the name of what are now called
proton
A proton is a stable subatomic particle, symbol , Hydron (chemistry), H+, or 1H+ with a positive electric charge of +1 ''e'' (elementary charge). Its mass is slightly less than the mass of a neutron and approximately times the mass of an e ...

Atomic number
The atomic number or nuclear charge number (symbol ''Z'') of a chemical element is the charge number of its atomic nucleus. For ordinary nuclei composed of protons and neutrons, this is equal to the proton number (''n''p) or the number of pro ...
