PRESENTATION OUTLINE
SCIENTISTS WHO DEVELOPED THE PERIODIC TABLE
1. Lavoisier
Antoine-Laurent de Lavoisier (also Antoine Lavoisier after the French Revolution; 26 August 1743 – 8 May 1794; French pronunciation: [ɑ̃twan lɔʁɑ̃ də lavwazje]) was a French nobleman and chemist central to the 18th-century Chemical Revolution and a large influence on both the histories of chemistry and biology.[1] He is widely considered to be the "Father of Modern Chemistry. His discovery of the role oxygen plays in combustion.
2. Dobereiner
Johann Wolfgang Döbereiner (13 December 1780 – 24 March 1849) was a German chemist who is best known for work that foreshadowed the periodic law for the chemical elements.
3. Chancourtois
Alexandre-Émile[1] Béguyer de Chancourtois (20 January 1820 – 14 November 1886) was a French geologist and mineralogist who was the first to arrange the chemical elements in order of atomic weights, doing so in 1862. De Chancourtois only published his paper, but did not publish his actual graph with the proposed arrangement.
4. John Newland
He was an english chemist who worked on the development of the periodic table.
5. Mendeleev
Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He formulated the Periodic Law, created his own 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.
6. Ramsay
The Scottish chemist William Ramsay (1852–1916) is known for work that established a whole new group in the periodic table, variously called over time the inert, rare, or noble gases. In the last decade of the 19th century, he and the famous physicist Lord Rayleigh (John William Strutt, 1842–1919)—already known for his work on sound, light, and other electromagnetic radiation—carried out separate investigations, for which they received Nobel Prizes in 1904, Ramsay in chemistry and Lord Rayleigh in physics.
7. Mosely
Henry Gwyn Jeffreys Moseley (23 November 1887 – 10 August 1915) was an English physicist. Moseley's outstanding contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley's law in X-ray spectra. Moseley's Law justified many concepts in chemistry by sorting the chemical elements of the periodic table of the elements in a quite logical order based on their physics.
