Part of Dmitri’s periodic table He realised that the physical and chemical properties of elements were related to their atomic mass in a ’periodic’ way‚ and arranged them so that groups of elements with similar properties fell into vertical columns in his table. He also stated: The elements‚ if arranged according to their atomic mass‚ exhibit an apparent periodicity
