Berzelius's analytical skills were put to the test when he and a colleague, Johan Gottlieb Gahn (1745–1818), noticed a residual substance while studying a method of producing sulfuric acid in 1817. They at first thought the substance was tellurium, but after careful quantitative analysis, they realized that they had isolated a new element.
These rocks contain valuable metals like silver (Ag) and copper (Cu). The Swedish chemist, Jons Jacob Berzelius (born 1779, died 1848; sketched at right→) wrote Dalton that the theory of multiple proportions is a mystery without the atomic hypothesis. By 1812 Berzelius had firmly established the Law of Multiple Proportions by analyzing a large number of examples and became a leading advocate for the atomic Jons Jacob Berzelius. The arrangement of elements in patterns paved the way to the tabulation of the element according to its chemical and physical properties suitably called the periodic table of elements.

Swedish chemist Jöns Jacob Berzelius (1779-1848) is widely credited with establishing several of these standard methods, while raising the sophistication of laboratory chemistry to new heights during the first half of the nineteenth century. Lived 1779 – 1848. Jacob Berzelius was one of the founders of modern chemistry. He was the first person to measure accurate atomic weights for the elements, which helped to confirm Dalton's Atomic Theory and was the basis of Mendeleev's periodic table.

In this effort, he built on the earlier work of many other chemists, notably Antoine Lavoisier (1743-1794), Humphry Davy (1778-1829), John Dalton (1766-1844) and Jacob Berzelius (1779-1848).
