WebHis newly formulated law was announced before the Russian Chemical Society in March 1869 with the statement “elements arranged according to the value of their atomic weights present a clear periodicity of properties.” Mendeleev’s law allowed him to build up a systematic table of all the 70 elements then known. WebThe Early Periodic Table John Dalton: (1765-1844) Arranged the elements in order of their masses. (Today it is Relative Atomic Mass) John Newland: In 1863, suggested the elements were to be arranged in octaves --> Similar to music; the eighth note resembles the first note.
