Berzelius demonstrated the use of an electrochemical cell to decompose certain chemical compounds into pairs of electrically opposite constituents. From this research, he articulated a theory that came to be known as electrochemical dualism, contending that chemical compounds are oxide salts, bonded together by electrostatic interactions.

Berzelius because his 1826 values are very close to the ones that are used today. 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 or isolated three elements, selenium, silicon, and thorium.

This work led to tables of atomic weights that were generally very accurate, but he never accepted Amedeo Avogadro's hypothesis and this led to some confusion.

Berzelius, John Dalton and Antoine Lavoisier are said to be the fathers of modern chemistry. 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. about his atomic theory – and his symbols. Berzelius’ initial scepticism about the atomic theory was based on his electrochemical experience. In that crucial year of 1808, he learned that Davy had electrolysed molten soda and potash, yielding the previously unknown metals potassium and sodium.

Atomic theory - History (1) by the application of the electro-chemical theory and the chemical proportions / By J. Jacob Berzelius . Brevväxlingen mellan Jöns Jacob Berzelius och Carl Palmstedt / utg. av Kungl. Jöns Jacob Berz

Swedish chemist who published a table of atomic weights ; contributed to electrochemical theory; discovered cerium , selenium , In order to establish and display the laws of stoichiometry, Berzelius invented and perfected more exacting standards and techniques of analysis. His generalization of the older acid/base chemistry led him to extend chemical nomenclature that Lavoisier had introduced to cover the bases (mostly metallic oxides), a change that allowed Berzelius to name any compound consistently with Lavoisier’s chemistry.

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.

The Swedish chemist Jöns Jacob Berzelius (1779-1848) is often considered, together with Robert Boyle, Antoine Lavoisier, and John Dalton, as one of the forefathers of modern chemistry. Even though he may not have the same name recognition as his illustrious peers, Berzelius was certainly a gifted and accomplished scientist.

Jöns Jacob Berz Jöns Jacob Berzelius This theory was founded on the supposition that the atoms of the elements are electrically polarized, the positive charge predominating although not so its theory or characteristics; nowadays it plays a fundamental role in 1835 by Jöns Jakob Berzelius (1779-1848), comes from the.
