dmitri mendeleev research paper

Dmitri Mendeleev in 1897 For the Russian Prime Minister with a similar name, see Dmitry Medvedev. This name uses Eastern Slavic naming customs; the patronymic is Ivanovich and the family name is Mendeleev. Dmitri Ivanovich Mendeleev[3] (/ˌmɛndəlˈeɪəf/;[4] Russian: Дми́трий Ива́нович Менделе́ев; IPA: [ˈdmʲitrʲɪj ɪˈvanəvʲɪtɕ mʲɪndʲɪˈlʲejɪf] ( listen); 8 February 1834 – 2 February 1907 O.S. 27 January 1834 – 20 January 1907) was a Russian chemist and inventor. He formulated the Periodic Law, created a farsighted version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered.

His grandfather was Pavel Maximovich Sokolov, a priest of the Russian Orthodox Church from the Tver region.[5] Ivan, along with his brothers and sisters, obtained new family names while attending the theological seminary.[6] Mendeleev was raised as an Orthodox Christian, his mother encouraging him to patiently search divine and scientific truth. [7] His son would later inform that he departed from the Church and embraced a form of deism.[8] Mendeleev is thought to be the youngest of either 11, 13, 14 or 17 siblings;[9] the exact number differs among sources.[10] His father was a teacher of fine arts, politics and philosophy. Unfortunately for the family's financial well being, his father became blind and lost his teaching position. His mother was forced to work and she restarted her family's abandoned glass factory. At the age of 13, after the.
Russian chemist Dimitri Mendeleev, who devised the atomic mass-based Periodic Table. RUSSIAN CHEMIST 1834–1907 Dimitri Ivanovich Mendeleev (or Mendeleyev or Mendelejeff) was born in Tobolsk, Siberia, on January 27, 1834. He was the fourteenth and youngest child of the family. His father was the director of the Tobolsk Gymnasium (high school). Tragedy plagued the family in Mendeleev's early years. His father became blind and was forced to retire from his job, and then unexpectedly died. His mother supported the family by managing a glass factory, but in 1848 it burned to the ground. His mother moved the family first to Moscow and then to St. Petersburg. In 1850 Mendeleev began his training as a teacher, following in his father's footsteps at the Pedagogical Institute in St. Petersburg. A few months after this, his mother and older sister died of tuberculosis. When Mendeleev graduated, he moved to Simferopol on the Crimean Peninsula to assume a post as a science teacher, but the school was soon closed because of the Crimean War. He returned to St. Petersburg and received a master's degree in 1856 after presenting his thesis Research and Theories on Expansion of Substances Due to Heat. The years 1859 to 1861, when the Ministry of Public Instruction sent him abroad to study, shaped Mendeleev's career as a scientist. He studied gas density with the chemist Henri Victor Regnault in Paris and spectroscopy with the physicist Gustav Kirchhoff in Heidelberg. It was while working in Heidelberg that Mendeleev discovered the principle of critical temperature for gases. Once a gas is heated to a temperature above its critical point, no amount of pressure will turn it into a liquid. His work went unnoticed, and the discovery of critical temperatures is usually attributed to the Irish physicist and chemist Thomas Andrews. Mendeleev also attended the 1860 Karlsruhe Congress, the.
Dmitry Ivanovich Mendeleyev, Mendeleyev also spelled Mendeleev    (born January 27 (February 8, New Style), 1834, Tobolsk, Siberia, Russian Empire—died January 20 (February 2), 1907, St. Petersburg, Russia), Russian chemist who developed the periodic classification of the elements. Mendeleyev 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 properties within groups of elements. In his version of the periodic table of 1871, he left gaps in places where he believed unknown elements would find their place. He even predicted the likely properties of three of the potential elements. The subsequent proof of many of his predictions within his lifetime brought fame to Mendeleyev as the founder of the periodic law.Early life and educationMendeleyev was born in the small Siberian town of Tobolsk as the last of 14 surviving children (or 13, depending on the source) of Ivan Pavlovich Mendeleyev, a teacher at the local gymnasium, and Mariya Dmitriyevna Kornileva. Dmitry’s father became blind in the year of Dmitry’s birth and died in 1847. To support the family, his mother turned to operating a small glass factory owned by her family in a nearby town. The factory burned down in December 1848, and Dmitry’s mother took him to St. Petersburg, where he enrolled in the Main Pedagogical Institute. His mother died soon after, and Mendeleyev graduated in 1855. He got his first teaching position at Simferopol in Crimea. He stayed there only two months and, after a short time at the lyceum of Odessa, decided to go back to St. Petersburg to continue his education. He received a master’s degree in 1856 and began to conduct research in organic chemistry. Financed by a government fellowship, he went to study abroad for two years at the University of Heidelberg.
