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.

Dimitri Mendeleev was born on February 8th, 1834.
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.
The modern periodic law was proposed by the Russian chemist Dmitri Mendeleev in 1869. He arranged the elements in order of increasing atomic mass and grouped them based on similar chemical properties, leading to the development of the periodic table.
He was Russian.
Mendeleev's published the periodic table in 1869.
The periodic table was formed in the 19th century by Dmitri Mendeleev in 1869. Mendeleev organized the elements based on their properties and atomic weights, creating the foundation for the modern periodic table we use today.
