DMITRI MENDELEEV, THE PERIODIC LAW OF THE CHEMICAL ELEMENTS1 Dmitri Mendeleev (1834–1907) was a Russian chemist best known for his contributions to the study of chemical elements and particularly the discovery of the periodic law and the creation of the periodic table. Mendeleev was born in a Siberian village near Tobolsk, Russia, the

The Discovery of the Periodic Table
discovery of new elements and theories, which eventually led to the development of the periodic table. It concludes by an analysis of the order of the discoveries made in chemistry during that period. It notes that many of the discoveries had to occur in a particular order and that the order of those discoveries was inevitable.

claims for discovery of elements 116, 118, 115, 113, and 117 in chronological order in the years up to 2010. The most recent discovery was published in [6]. A sum-mary of all results of the Dubna experiments has been presented in [7]. Another claim on the discovery of element 113 was submitted by a Japanese-Chinese

In 1869 Russian chemist Dimitri Mendeleev started the development of the periodic table, arranging chemical elements by atomic mass. He predicted the discovery of other elements, and left spaces open in his periodic table for them. In 1886 French physicist Antoine Bequerel first discovered radioactivity. Thomson student from New Zealand Ernest

in the periodic table. Introduction In nineteenth century, chemists devoted much of their efforts in attempts to arrange elements in a systematic manner. These efforts resulted in discovery of periodic law. On the basis of this law, the elements known at that time, were arranged in the form of a table which is known as periodic table.
