Who invented the periodic table? Dmitri Mendeleev invented the periodic in 1869‚ 5 years after John Newlands put forward his law of Octaves. 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
