Solution
The correct option is D D. I. Mendeleev
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.
The properties of the elements, as well as the formulae and properties of their compounds, depend in a periodic manner on the atomic weights of the elements. This periodic law was given by D.I. Mendeleev.
Hence, option D is the correct answer.
