2021-02-19 · Jöns Jacob Berzelius, (born Aug. 20, 1779, near Linköping, Swed.—died Aug. 7, 1848, Stockholm), one of the founders of modern chemistry. He is especially noted for his determination of atomic weights, the development of modern chemical symbols, his electrochemical theory, the discovery and isolation of several elements, the development of classical
3. Berzelius was in many ways the most influential chemist of the first half of the 19thcentury. He developed a dualistic theory of chemical bonding, based on the electrical polarities of elements. He introduced the concepts of allotropy, catalysis, and isomerism.

He discovered three chemical elements: cerium, thorium, and selenium, and devised the modern method by which one or two letters are used to symbolize the elements. The most notable of Berzelius's contributions to chemistry was his development of a rational system of atomic symbols.

Remarking on the unkempt appearance of the university students, he wrote: Berzelius is credited with the experimental substantiation of atomic theory and its development and introduction in chemistry. During the years 1810–1816, Berzelius used materials from analyses of oxides and provided new evidence for the law of multiple proportions. Berzelius is credited with the experimental substantiation of atomic theory and its development and introduction in chemistry. During the years 1810–1816, Berzelius used materials from analyses of oxides and provided new evidence for the law of multiple proportions. 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. The history of modern atomic theory begins with an unexpected person, a young school principal, member of the Quaker cult, named John Dalton.In his article for the Manchester Literary and Philosophical Society in 1803, Dalton presented the relative atomic weight of some of the most important chemical elements known to that day.

Jöns Jacob Berzelius, ein berühmter Chemiker, ein unbekannter Arzt : eine Studie atomteorin = Berzelius and the chemical atomic theory / Anders Lundgren.
Berzelius, John Dalton and Antoine Lavoisier are said to be the fathers of modern chemistry. Berzelius was born in Linköping in Östergötland in Sweden.
The most notable of Berzelius's contributions to chemistry was his development of a rational system of atomic symbols. Around 1810 Berzelius was working to confirm John Dalton's atomic theory as well as Proust's law showing that separate elements always combined in whole-number proportions.
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 […] John Jacob Berzelius 1.
