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 … Web16. Of course Mendeleev had no idea about protons or electrons. It is he who discovered the integer which we call atomic number, and which was later found to be the number of protons. The story of this discovery is approximately this. He was preparing to his chemistry course where he was supposed to give a survey of elements.

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. WebThe proton remember is the sub atomic particle in the nucleus and any atoms with the same number of protons are the same element.
