In 1893, he was director of the Central Board of Weights and Measures in Russia. He published several articles in the Brockgas encyclopedia and reprinted many of his principles of chemistry.

The revolutionary organization of his elements correctly assumed that the atomic weight of some elements was wrongly measured and that there were eight new elements. His scientific fame increased with the discovery of new elements and his theories proved more accurate. Periodic Table The British Royal Society honored him with this famous scientific discovery. He died on 2 February 1907 at the age of 72 in St. Petersburg’s Russian Empire. The 101st element was discovered in 1955. It was named Mendelevium for his contributions to science.
