Here is where he first sees that the periodic table is a display of chemical periodicity that is itself a function of the variation of atomic weight. Mendeleev found that, when all the known chemical elements were arranged in order of increasing atomic weight, the resulting table displayed a recurring pattern, or periodicity, of properties within groups of elements. He called his table or matrix mendeleev also investigated the composition of petroleum, and helped to found the first oil.
