  • Lothar Mayer

    Lothar Meyer develops an early version of the periodic table, with 28 elements organized by valence

  • Dmitri Mendeleev

    Dmitri Mendeleev produced a table based on atomic weights but arranged 'periodically' with elements with similar properties under each other. His Periodic Table included the 66 known elements organized by atomic weights.

  • Henry Moseley

    Henry Moseley determined the atomic number of each of the elements and modified the 'Periodic Law'.

  • Glenn Seaborg
