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. He discovered three chemical elements: cerium, thorium, and selenium, and devised the modern […]

He was a professor of chemistry and pharmacy and this system of notations helped him to show the chemical composition easily to his medical students. 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.

For example, Berzelius‘ electrochemical theory, which interpreted all chemical bonding in terms of the attraction of fragments (‘atoms’) of opposing charges, stemmed from Berzelius’ titanic work on oxides and salts to draw up an accurate table of atomic weights.

Jons Jacob Berzelius was a Swedish chemist born on August 20, 1779 – died on August 07, 1848. Berzelius was best known for his determination of atomic

Working in a laboratory with facilities no more elaborate than a kitchen, Berzelius prepared and purified the necessary reagents, developed the techniques to perform the analyses, and collected data on the relative weights of atoms of 43 elements. 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 hypothesis. Jöns Jacob Berzelius. The Swedish chemist Jöns Jacob Berzelius (1779-1848) was one of the first European scientists to accept John Dalton's atomic theory and to recognize the need for a new system of chemical symbols. He was a dominant figure in chemical science. Berzelius gave the oxygen arbitrary atomic mass 100 and referred all other atomic masses on the oxygen. Later he chose as a reference point and the hydrogen.
