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 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.

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. 2017-12-01 The overall view of Berzelius’s career was “dualism”. His theory was, that since compounds were decomposed by an electrical current and released elements were formed at the poles in an electrolytic cell, he assumed that atoms were charged and chemical combinations resulted from the neutralization of opposite charges. 2021-02-19 The most notable of Berzelius's contributions to chemistry was his development of a rational system of atomic symbols.

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. Repeating Davy’s experiments,
