WebIntroduction. Two to one-and-half centuries ago, authors of chemistry books and chemistry teachers such as Leopold Gmelin (Gmelin, 1843), Lothar Meyer (Meyer, 1864), Dmitri Mendeleev (Mendeleev, 1869b) and Viktor von Richter (Von Richter, 1875) felt the need for an ordered arrangement of the increasing number of elements.They addressed this … WebIn his writings, he never used the term ‘periodic table’ for his system, instead using the terminology ‘periodicity of the elements’ or the ‘periodic law of the elements’. As his, and subsequent investigators’, orderings were presented as ‘tables of ordered elements’ and the like, the term ‘periodic table’ came into use after Dmitri’s time.
