Becky Graessle, Nikki Johnson, and Taylor Falkowski
He was born in Tobolsk, Siberia on February 8, He died on February 2, Studied science at St. Petersburg University and graduated in1856.
He had six children in total, two with his first wife, Feozva Nikitchna Lascheva. They had two children, a boy named Volodya, and a daughter named Olga. In January 1882, he divorced Feozva so he could marry Anna Ivanova Popova(his niece's best friend). They had four children: Liubov, Ivan, and twins Vassili and Maria
The First Founder of the Periodic Table. His first Periodic Table was assembled by arranging the elements in “ascending order of atomic weight and grouping them by similarity of properties.” He left room for more elements, and predicted 3 yet to be discovered elements. He defined the absolute point of ebullition, or the point at which a gas in a container will condense to a liquid by adding pressure. He was awarded the medal of excellence for being first in his class at St. Petersburg.
He was one of the founding members of the Russian Chemical Society in He helped “open the lines of communication between scientists in Europe and the United States.” Mendeleev was one of the first scientists that did not rely solely on his own work but was in correspondence with scientists around the world. He then used their data along with his own data to arrange the elements according to their properties.
Davy Medal from the Royal Society of England in Following his resignation from the University of St. Petersburg, the Russian government in 1893 appointed him Director of the Bureau of Weights and Measures. Copley Medal, the Society's highest award, in 1905, Honorary degrees from universities around the world.

In 1859, the Minister of Public Instruction assigned him to study and develop scientific and technological innovations overseas. Between 1859 and 1861 he studied the densities of gases with Regnault in Paris and the workings of the spectroscope with Kirchoff in Heidelberg, Germany. He also pursued studies of capillarity and surface tension that led to his theory of "absolute boiling point," later known as critical temperature.
Mendeleev created the Periodic Law. It states that the physical and chemical properties of the elements arrange systematically with increasing atomic number. By 1869Mendeleev had assembled detailed descriptions of more than 60 elements. On March 6, 1869 a formal presentation was made to the Russian Chemical Society entitled "The Dependence Between the Properties of the Atomic Weights of the Elements,”(Mendeleev was unable to present it because he was bed-ridden.
On November 29, 1870, Mendeleev stated that it was possible to predict the properties of undiscovered elements. He then proceeded to make predictions for three new elements (eka-aluminum, eka- boron and eka-silicon) and suggested several properties of each, including density, radii. No one really believed Mendeelev’s predictions until November, 1875, when the Frenchman Lecoq de Boisbaudran discovered one of the predicted elements (eka-aluminum) which he named Gallium.
