Svante August Arrhenius A Swedish physical chemist, Svante August Arrhenius (1859-1927) was born near Uppsala, he became a professor at Stockholm in 1895, and his special study was Electrolysis . He developed the theory concerning the properties of ionic species in solution. They are Arrhenius Concept of Bases Arrhenius Concept of Neutralisation and Arrhenius Concept of Acids He wrote "Worlds in the Making and Destinies of the Stars" He was awarded the Nobel Prize for Chemistry in 1903AD. In 1905 he predicted global warming as a result of carbon dioxide emission from burning fuels. Francis William Aston A British physicists, Francis William Aston (1877-1945) invented the Mass Spectrometer and used it to identify and separate the Isotopes , of elements, for which he was awarded the Nobel prize for Chemistry in 1922. Count Amedeo Avogadro An Italian physicist, Count Amedeo Avogadro, published his hypothesis in 1811AD, which states that equal volumes of gases under the same conditions of temperature and pressure contain the same number of molecules. His work was revived by Cannizzaro The Avogadro's Number , N, 6.02 X 10^23 is the number of molecules in one mole of a substance.

In 1910 he went to Cambridge to work under J. J. Thomson. Aston's mass spectrograph showed that most stable elements were a mixture of isotopes, differing in mass but not in chemical properties. Using this device he was able to discover 212 of the 287 stable isotopes. Aston was awarded the Nobel Prize in 1922.

Nobel Prize Winning Chemists Francis William Aston The Nobel Prize in Chemistry 1922 Francis William Aston was born in September 1877 at Harborne, Birmingham, England, the third of a family of seven children. His winning of the Forster Scholarship in 1898 properties of tartaric acid derivatives; the results of this work were published in 1901. In 1903 he obtained a scholarship to Birmingham University to work on the properties of the Crookes Dark Space in discharge tubes. Within a short time he had discovered the phenomenon which is known as the Aston Dark Space. It was during this period that he obtained definite evidence for the existence of two isotopes of the inert gas neon. In 1919, he again attacked the problem of the separation of the isotopes of neon. He quickly achieved success in this by his invention of the mass spectrograph, an apparatus in which the ingenious use of electromagnetic focusing enabled him to utilize the very slight differences in mass of the two isotopes to effect their separation. Extending this principle to other chemical elements, he discovered, in a series of measurements, no less than 212 of the naturally occurring isotopes. From the results of this work he was able to formulate the so-called Whole Number Rule which states that, the mass of the oxygen isotope being defined, all other isotopes have masses that are very nearly whole numbers.

Francis William Aston Francis William Aston was born in September 1877 at Harborne, Birmingham, the third of a family of seven children. He was educated at Harborne Vicarage School and Malvern College where his interest in science was aroused. In 1894 Aston entered Mason College, Birmingham (later to become the University of Birmingham) where he studied chemistry under Frankland and Tilden, and Physics under Poynting. His winning of the Forster Scholarship in 1898 enabled him to work on the optical properties of tartaric acid derivatives; the results of this work were published in 1901. Leaving academic life for a time, he worked for three years as a chemist in the laboratory of a brewery. At about this time, however, his interest in physics, rather than chemistry, began to predominate; his aptitude for mechanical contrivance showed itself in his design and construction of new types of pumps for evacuating vessels. From this stemmed his interest in gas discharge phenomena in evacuated tubes. In 1903 he obtained a scholarship to Birmingham University (as it had now become) to work on the properties of the Crookes Dark Space in discharge tubes. Within a short time he had discovered the phenomenon which is known as the Aston Dark Space. At the end of 1909 he accepted the invitation of Sir J.J.Thomson to work as his assistant at the Cavendish Laboratory, Cambridge, on studies of positive rays. It was during this period that he obtained definite evidence for the existence of two isotopes of the inert gas neon.

Francis William Aston (Harbone, 1877 - Londres, 1945) Físico inglês. Forma-se em Birmingham e em Cambridge, onde trabalha com Joseph John Thomson na investigação às descargas eléctricas em tubos de baixa pressão. Exerce como professor no Trinity College de Cambridge. Em 1921 ingressa na Royal Society e em 1935 é nomeado presidente do Comité Internacional Atómico. No decurso das suas investigações sobre os isótopos inventa o espectrógrafo de massas (1919). Este elemento de investigação, que tem o seu nome («espaço escuro de Aston»), permite a separação dos isótopos e a determinação das suas massas com uma milésima de aproximação. Os seus contributos principais para a física são a determinação da carga eléctrica dos iónios e uma importante contribuição para a descoberta dos isótopos. Recebe o Prémio Nobel de Química em 1922. Os seus livros principais são Os Isótopos e Espectros de Massas e Isótopos
