Klickstein, eds., A Source Book in Chemistry, 1400-1900 (1952); and Isaac Asimov, A Short History of Chemistry: An Introduction to the Ideas and Concepts of Chemistry (1965). It also allowed for the calculation of the molecular weights of gases relative to some chosen standard. He married Donna Felicita Mazzi, by whom he had six sons. The scientific community did not give great attention to Avogadro's theory, and it was not immediately accepted. 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.

On the basis of this type of evidence, Avogadro drew the logical conclusion that the number of "integrant molecules" in all gases is always the same for equal volumes. 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.

Avogadro also served Italy as a competent and honest civil servant. Furthermore, as similar atoms were thought to repel one another, the existence of polyatomic elementary molecules seemed unlikely. The results ranged from 0.8595 for oxygen to 10.2672 for hydrogen, and the numerical order of the affinities coincided with the electrochemical series, which listed the elements in the order of their chemical reactivities.

Three years later he described the formulas for carbon dioxide, carbon disulfide, sulfur dioxide, and hydrogen sulfide. Born in Turin on Aug. 9, 1776, Amedeo Avogadro came from an ancient legal family, whose name derived from the Latin de advocatis (concerning the law). Co-author of, Stanislao Cannizzaro: Atomic weights and Avogadro. Cannizzaro’s historical significance is most closely associated with a long letter he wrote on March 12, 1858, to his friend Sebastiano de Luca, professor of chemistry at Pisa, and subsequently published as “Sunto di un corso di filosofia chimica fatto nella R. Università de…. Two years later, because of the turmoil gripping the country, the chair was suppressed.

Avogadro was the son of Filippo Avogadro, conte di Quaregna e Cerreto, a distinguished lawyer and senator in the Piedmont region of northern Italy. Avogadro developed this hypothesis after Joseph Louis Gay-Lussac published his law on volumes (and combining gases) in 1808. Overview In 1809 he was appointed professor of physics in the Royal College at Vercelli. Crossword Answers (1) He believed that there were three kinds of "molecules," including an "elementary molecule" (our "atom"). He explained that these exceptions were due to molecular dissociations at certain temperatures, and that Avogadro's law determined not only molecular masses, but atomic masses as well.
