On March 6, 1869, Mendeleev made a formal presentation to the Russian Chemical Society, entitled The Dependence between the Properties of the Atomic Weights of the Elements, which described elements according to both weight and valence.
_________________________________________________________________________ In1869, Mendeleev published the first Periodic Table. Within 16 years, chemists discovered the three missing elements scandium, gallium, and germanium. Their properties are close to those that Mendeleev had predicted.Over all he discovered the three new or missing elements.

When Dmitri Mendeleev died, they draped a copy of the periodic table over the coffin and buried it with him. Mendeleev was born in 1834 and died in 1907.

I believe it was Dimitri Mendeleev. Alex was here
Dimitri Mendeleev did the original in 1869. The last naturally occurring element was Francium, and it allows for the addition of elements that were discovered later.
Dmirtri Mendeleev made the first periodic table. It was organized by elements according to the atomic mass. < notice it is atomic mass not number>
He was Russian.
Mendeleev's published the periodic table in 1869.
The Russian chemist Dmitri Mendeleev was the first scientist to make a periodic table similar to the one used today.
