order of an element in Mendeleyev's table of the elements; equal to the number of protons in the nucleus or electrons in the neutral state of an atom of an element atomic number
cyclotron that accelerates protons up to several billion electron volts bevatron
(physics) the interaction that binds protons and neutrons together in the nuclei of atoms; mediated by gluons color force , strong force , strong interaction
highly penetrating ionizing radiation of extraterrestrial origin; consisting chiefly of protons and alpha particles; collision with atmospheric particles results in rays and particles of many kinds cosmic ray
