Dmitri Ivanovich Mendeleev (/ ˌ m ɛ n d əl ˈ eɪ ə f / MEN-dəl-AY-əf; [2] [b] [a] 8 February [O.S. 27 January] 1834 – 2 February [O.S. 20 January] 1907) was a Russian chemist known for formulating the periodic law and creating a version of the periodic table of elements.
Dmitri Mendeleev (1834–1907) [70] Arranged the sixty-six elements known at the time in order of atomic weight by periodic intervals (1869). Physical chemistry: Mikhail Lomonosov (1711–1765) The first to read lectures in physical chemistry and coin the term (1752). Jacobus van 't Hoff (1852–1911)
Its discovery is generally believed to have originated in India around the 4th century AD, ... 1869: Dmitri Mendeleev: Periodic table. 1871: Lord Rayleigh: ...
March 6 – Dmitri Mendeleev makes a formal presentation of his periodic table to the Russian Chemical Society. June 15 – John Wesley Hyatt patents celluloid , in Albany, New York . July 15 – Hippolyte Mège-Mouriès files a patent for margarine (as oleomargarine ) in France as a beef tallow and skimmed milk substitute for butter.
Gallium is discovered spectroscopically by French chemist Paul Emile Lecoq de Boisbaudran. Later in this year he obtains the free metal by electrolysis of its hydroxide and names it. This is the first of Dmitri Mendeleev's predicted elements to be identified. [1] [2] [3] Phenylhydrazine is discovered by Hermann Emil Fischer. [4]
The medal has been awarded to multiple individuals in the same year: in 1882, for example, it was awarded to Dmitri Mendeleev and Julius Lothar Meyer "for their discovery of the periodic relations of the atomic weights"; [6] in 1883 to Marcellin Berthelot and Julius Thomsen "for their researches in thermo-chemistry"; [6] in 1893 to Jacobus ...
Pyrocollodion is a smokeless powder invented by Dmitri Mendeleev. A variant of the nitrocellulose family of compounds, it was discovered by Dmitri Mendeleev in 1892. He had proposed its use as a replacement for gunpowder in the Russian Navy. This offer was rejected because of cost and efficiency considerations.
Universal gas constant was discovered and first introduced into the ideal gas law by Dmitri Mendeleev in 1874<ref> Mendeleev, D. I. (1874). "О сжимаемости газов (On the compressibility of gases)". Russian Journal of Chemical Society and the Physical Society. 6: 309– 352.
