By continuing, you agree to our He used this hypothesis further to explain the French chemist Joseph-Louis Gay-Lussac’s law of combining volumes of gases (1808) by assuming that the fundamental units of elementary gases may actually divide during chemical reactions. Modest and retiring, he was indifferent to honors and scrupulously avoided those public struggles for priority which were a characteristic of Continental scientific society in the mid-19th century. He also applied his hypothesis to metals and assigned atomic weights to 17 metallic elements based upon analyses of particular compounds that they formed.

Amedeo Avogadro, in full Lorenzo Romano Amedeo Carlo Avogadro, conte di Quaregna e Cerreto, (born August 9, 1776, Turin, in the Kingdom of Sardinia and Piedmont [Italy]—died July 9, 1856, Turin), Italian mathematical physicist who showed in what became known as Avogadro’s law that, under controlled conditions of temperature and pressure, equal volumes of gases contain an equal number of molecules.

André-Marie Ampère proposed a very similar theory three years later (in his Sur la détermination des proportions dans lesquelles les corps se combinent d'après le nombre et la disposition respective des molécules dont leurs particules intégrantes sont composées; "On the Determination of Proportions in which Bodies Combine According to the Number and the Respective Disposition of the Molecules by Which Their Integral Particles Are Made"), but the same indifference was shown to his theory as well.

Comments (0), This site uses cookies for analytical and advertising purposes. Mathematically dividing an element’s affinity for heat by that of his selected standard, oxygen, resulted in what he termed the element’s “affinity number.” Between 1843 and his retirement in 1850, Avogadro wrote four memoirs on atomic volumes and designated affinity numbers for the elements using atomic volumes according to a method “independent of all chemical considerations”—a claim that held little appeal for chemists. Please select which sections you would like to print: Corrections? This was finally resolved by Stanislao Cannizzaro, as announced at Karlsruhe Congress in 1860, four years after Avogadro's death. Omissions?

Weight of 1 volume of gas or vapour /Weight of 1 volume of hydrogen = Weight of 1 molecule of gas or vapour /Weight of 1 molecule of hydrogen. Avogadro developed this hypothesis after Joseph Louis Gay-Lussac published his law on volumes (and combining gases) in 1808. Another confusing aspect of the Avogadro memoir was the use of the ambiguous term "molecule." Home-loving, industrious, and modest, he rarely left Turin. He believed that there were three kinds of "molecules," including an "elementary molecule" (our "atom").

He held positions in the National Bureau of Statistics, helped to establish a national meteorological service, and in 1848 became a member of the Superior Council on Public Instruction. The greatest problem Avogadro had to resolve was the confusion at that time regarding atoms and molecules. Italian physicist noted for his work on gases; proposed what has come to be called Avogadro's law (1776-1856) Contribute an answer We do our best to have all the answers for Amedeo , Italian physicist noted for his contributions to molecular theory .

In honor of Avogadro's contributions to molecular theory, the number of molecules per mole of substance is named the "Avogadro constant", NA. Avogadro submitted this essay to Jean-Claude Delamétherie's Journal de Physique, de Chimie et d'Histoire naturelle ("Journal of Physics, Chemistry and Natural History"). Best of all, you can solve any crossword puzzle online! Jacobus Henricus van 't Hoff showed that Avogadro's theory also held in dilute solutions. Avogadro also mathematically represented his findings in ways more familiar to physicists than to chemists. This lack of interest was due in part to the novelty of the atomic theories which had been presented to the world a few years before by John Dalton; furthermore, the methodological temper of the times, deeply experimentalistic and empirical, prevented careful consideration of a purely logical inference from chemical facts unsupported by masses of laboratory data. Priority over who actually introduced the molecular hypothesis of gases was disputed throughout much of the 19th century. In 1820, he became a professor of physics at the University of Turin. Although his gaseous elementary molecules were predominantly diatomic, he also recognized the existence of monatomic, triatomic, and tetratomic elementary molecules.
