Autobiography of A Vogadro

"molecules" and "elementary molecules" (atoms but he was able to use these ideas to explain the strange results obtained when hydrogen and oxygen gas reacted together to form water vapor. The theories of better known scientists of the time, like John Dalton and Jöns Jacob Berzelius, disagreed with Avogadros work. The chair was reestablished in 1832 and offered to the French mathematical physicist. Avogadro, however, saw it as the key to a better understanding of molecular constituency. 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 Italydied July 9, 1856, Turin Italian mathematical physicist who showed in what became known. Other methods developed in the following years are based on Millikan's oil drop experiment (1917, N,.064(6) 1023 mol-1 on the counting of alpha particles emitted from radium or uranium (Rutherford (1909 N,.16 1023 mol-1) and on investigations of molecular monolayers on liquids (Nuoy. It is now called Avogadros law. For example, 12 grams of carbon contains.02214129 x 1023 carbon atoms. Many years of research work were centred on the problem of how far the perfection of a real crystal is away from the ideal state.

In 1806, aged 30, Avogadro abandoned his successful legal practice and started teaching mathematics and physics at a high school in Turin. Excited by his own ideas, Avogadro then went through all the literature published in his journals (particularly the experiments reported by Gay-Lussac) and explained all the measured gas results in terms of his new hypothesis. macroscopic density, isotopic composition, and unit cell volume of a silicon crystal. Avogadros hypothesis began to gain broad appeal among chemists only after his compatriot and fellow scientist Stanislao Cannizzaro demonstrated its value in 1858, two years after Avogadros death. As a result of these observations Avogadro became the first scientist to realize that elements could exist as molecules rather than as individual atoms. Three years later he became professor of natural philosophy at the Royal College of Vercelli, a post he held until 1820 when he accepted the first chair of mathematical physics at the, university of Turin. In addition, Avogadro was not part of an active community of chemists: the Italy of his day was far from the centers of chemistry in France, Germany, England, and Sweden, where Berzelius was based.
