The Russian chemist Dmitri Mendeleev was the first scientist to make a periodic table similar to the one used today. [citation needed] Mendeleev arranged the elements by atomic mass, corresponding to relative molar mass.
The Periodic TableDmitri Mendeleev created the first periodic table according to atomic mass in 1869. Others before Mendeleev had organized the elements according to their pro â¦ perties and were able to discern periodicity, although Mendeleev is generally accepted as the creator of the table.endeleev intended the table to illustrate recurring (periodic) trends in the properties of the elements. The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior.
