Making the world better, one answer at a time. Stanislao Cannizzaro, an Italian chemist who worked with Dmitri, inspired Dmitri Mendeleev to come up with his creative ideas. Atomic Weight also inspired Mendeleev.
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.
