WebHistory of the Atom Development of the Periodic Table In the early 1800s, elements were arranged by atomic mass. The periodic table was not complete because some of the elements had not been found. Some elements were put in the wrong group. Dimitri Mendeleev (1869) left gaps in the periodic table. He put them in order of atomic mass. WebQuestion 1a. John Newlands first began developing the idea of a periodic table of elements around 140 years ago.
