WebJan 7, 2024 · Mendeleev ostensibly organized his table by increasing atomic weight, but he gave chemical properties a deciding vote. For example, tellurium is slightly heavier than iodine, but Mendeleev put tellurium first because it has the same valence as oxygen, sulfur, and other elements in its group. Tables have retained that ordering. 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.

WebIt is also worthy to note that Mendeleev's 1871 arrangement was related to the atomic ratios in which elements formed oxides, binary compounds with oxygen whereas today's periodic tables are arranged by increasing …
WebThe periodic table was arranged by atomic mass, and this nearly always gives the same order as the atomic number. However, there were some exceptions (like iodine and tellurium, see above), which didn’t work. Mendeleev had seen that they needed to be swapped around, but it was Moseley that finally determined why.
