The Russian scientist Vasili Samarsky-Bykhovets has what pioneering connection with the periodic table of elements?
"Vassili Samarsky-Bykhovets Vasili Evgrafovich Samarsky–Bykhovets (; November 7, 1803 – May 31, 1870) was a Russian mining engineer and the chief of Russian Mining Engineering Corps between 1845 and 1861. The mineral samarskite (samarskite-Y, samarskite-Yb and calciosamarskite), and chemical element samarium are named after him. He was the first person whose name was given to a chemical element. Samarsky–Bykhovets was born in a noble family in the Tomsk Governorate, located in the Asian part of Russia beyond the Ural Mountains. He received military engineer education at the local Mining Cadet Corps, and after graduation in 1823 served in a military"
"118 confirmed elements as of 10 April 2010. Although earlier precursors to this presentation exist, its invention is generally credited to the Russian chemist Dmitri Mendeleev in 1869, who intended the table to illustrate recurring 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. Use of the periodic table is now ubiquitous within the academic discipline of chemistry, providing an extremely useful framework to classify, systematize and compare all the many different forms"

Mendeleev, a Russian chemist, felt that there was some type of order to the elements and he spent more than thirteen years of his life collecting data and assembling the concept, initially with the idea of resolving some of the disorder in the field for his students. Mendeleev found that, when all the known chemical elements were arranged in order of increasing atomic weight, the resulting table displayed a recurring pattern, or periodicity, of"

The Russian chemist Dmitri Mendeleev was the first scientist to make a periodic table similar to the one used today. Mendeleev arranged the elements by atomic mass, corresponding to relative molar mass. It is sometimes said that he played 'chemical solitaire' on long train journeys, using cards with various facts about the known elements. On March 6, 1869, Mendeleev gave a formal presentation, ""The Dependence Between the Properties of the Atomic Weights of the Elements"", to the Russian Chemical Society. In 1869, the table was published"
"History of the periodic table The periodic table is an arrangement of the chemical elements and are organized on the basis of their atomic numbers, electron configurations and recurring chemical properties. Elements are presented in order of increasing atomic number. The standard form of the table consists of a grid of elements with rows called periods and columns called groups. The history of the periodic table reflects over a century of growth in the understanding of chemical properties. The most important event in its history occurred in 1869, when the table was published by Dmitri Mendeleev, who built upon earlier"

This format is still used by many, as shown by this contemporary Russian short form table, which includes all elements and element names until roentgenium. H. G.

Two years later, Mendeleev revised his table, placing hydrogen in group 1 above lithium, and also moving thallium to the boron group. In this 1871 version, copper, silver, and gold were placed twice, once as part of group IB, and once as part of a ""group VIII"" encompassing today's groups 8 to 11.

He named them eka-boron, eka-aluminium and eka-silicon with atomic masses 44, 68 and 72 respectively.
