Explaining this phenomenon, Becquerel called the yellow-red continuing rays (""rayon continuateurs"") in contrast to the primary rays, which exicited or produced the light image and which he called exiciting rays (""rayons excitateurs"").... They are dependent on the wave lenght of the light.""(Eder ""History of Photography"", pp. 265 ff.)""Becquerel was an early experimenter in photography. In 1840 he discovered that the silver halides, natively insensitive to red and yellow light, became sensitive to that part of the spectrum in proportion to their exposure to blue, violet and ultraviolet light, allowing Daguerreotypes and other photographic materials to be developed by bathing in strong red or yellow light rather than by chemical treatment. In practice this technique was rarely used."" (Wikipedia).‎

This was the starting point of his complete new system of chemistry, first briefly sketched in Recherches sur les lois de l’affinité (1801) and later developed into the comprehensive, two volume Essai de statique chimique. Here he attempted to provide a proper basis for chemistry, so that its experimental results could be viewed in the light of theoretical first principles. Berthollet developed a theory and a model adequate for the understanding and the interpretation of the rapidly growing body of chemical knowledge in his time. He was aware that the positive work of constructing a new theory had yet to be performed after the shock of Lavoisier’s criticism of the old chemistry.(DSB).Parkinson ""Breakthroughs"", 1801 C.‎

The mineral turned out to be thorium silicate, and it is now known as thorite. Berzelius even produced a sample of metallic thorium by heating thorium fluoride with potassium, and confirmed it as a new metal. He called the black mineral thorite, in honor of the Scandinavian god Thor.Parkinson ""Breakthroughs"", 1829 C.‎

‎The papers represents one of the first announcements of Berzelius' discovery of the fixed chemical proportions, determining the weights and valencies of the various constituent elements in inorganic compounds. The papers were published at the same time in Swedish, German (both here in Annalen and in Schweiger's Journal), and in French. By running many hundreds of analysis of chemical compounds he gave so many examples of the law of definite proportions that the world of chemistry could no longer doubt its validity, and in so doing he gave experimental evidence to the atomic theory. He hereby laid a solid fundation for the further development of chemistry. A reprint is found in Ostwald's Klassiker der exakten Wissenschaften, No. 35.According to Söderbaum (Jac. Berzelius, 2, p.12) ""It was a giant work, one of the most importent in the history of chemistry, which was here presented. One is even more impressed when one remembers that it was a pioneer undertaking in every sense of the term. Analytic and synthetic methods existed before Berzelius' time, to be sure, but there were no precise methods of the sort which he required. They all had to be elaborated at the cost of time and labour.""(J. Erik Jorpes ""Jac. Berzelius"", p.45).""In general Berzelius's efforts were directed toward the consolidation and extension of the atomic theory. He improved chemical analysis and determined the composition of a large number of compounds, thus verifying the laws of constant and multiple proportions and furnishing the most accurate equivalent weights then available. By ingenious methods he arrived at the correct atomic composition of most common substances, and thus was enabled to draw up (in 1826) a table of atomic weights very nearly identical with the modern one.""(Leicester & Klicktein ""A Source Book in Chemistry"", p. 258).Parkinson ""Breakthroughs"", 1810-20 C.‎
