29 nov. 2011 — Han var en av sin tids världsledande kemister. Inte nog med att Jöns Jacob Berzelius fann fyra nya grundämnen, han skapade också den
The next step in preparing the way for the Periodic Table was the development of exact analytical methods to give precise atomic weights. 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.

Although Berzelius began his career as a physician, his enduring contributions were in the fields of electrochemistry, chemical bonding and stoichiometry. In particular, he is noted for his determination of atomic weights and his experiments that led to a more complete understanding of the principles of stoichiometry, which is the branch of chemistry pertaining to the quantitative relationships between elements in chemical compounds and chemical reactions and that these occur in definite Jöns Jakob Berzelius. An avid and methodical experimenter, Jöns Jakob Berzelius (1779–1848) conducted pioneering experiments in electrochemistry and established the law of constant proportions, which states that the elements in inorganic substances are bound together in definite proportions by weight.
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 […]
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. 2021-02-19 · Jöns Jacob Berzelius, 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 analytical techniques,
