Isotopes‚ sub-atomic particles and relative atomic mass Sub-atomic particles A subatomic particle is a particle smaller than an atom: it may be elementary or composite. In 1905‚ Albert Einstein demonstrated the physical reality of the photons‚ hypothesized by Max Planck in 1900‚ in order to solve the problem of black body radiation in thermodynamics. In 1874‚ G. Johnstone Stoney postulated a minimum unit of electrical charge‚ for which he suggested the name electron in 1891. In 1897‚ J. J. Thomson confirmed
