On 17 February 1869, Russian chemist Dmitri Mendeleev jotted down the symbols for the chemical elements, putting them in order according to their atomic weights and inventing the periodic table.

The modern periodic table, arranged in rows and columns, was first introduced by Dmitri Mendeleev in 1869. At the time, it included the known elements and their properties, but Mendeleev predicted ...

Consequently the oxide must have the formula InO3 and the atomic weight must be about 114. discrepances in the periodic table. It was already observed by Mendelejeff that a discrepancy exists in ...
