What did berzelius do?
Berzelius is best known for his system of electrochemical dualism. The electrical battery, invented in 1800 by Alessandro Volta and known as the voltaic pile, provided the first experimental source of current electricity.

Where can cerium be found?
Cerium occurs in bastnasite, monazite, and many other minerals. It also is found among the fission products of uranium, plutonium, and thorium. Cerium is about as abundant as copper and nearly three times as abundant as lead in the igneous rocks of Earth’s crust.
What information did jöns Jakob Berzelius publish that gave scientists the ability to attempt to organize the elements for the first time?
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.
Where was Jons Jacob Berzelius born and died?
Jöns Jacob Berzelius, (born Aug. 20, 1779, near Linköping, Swed.—died Aug. 7, 1848, Stockholm), one of the founders of modern chemistry.
How did Jacob Berzelius contribute to modern chemistry?
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,…
Why was Jons Jacob Berzelius awarded a baronetcy?
In recognition of his growing international reputation, Berzelius was elevated to a position of nobility in 1818 on the coronation of King Charles XIV John. He was awarded a baronetcy in 1835 upon his marriage to Elizabeth Poppius.
How did Jons Jacob Berzelius develop his system of notation?
The project of specifying substances also led Berzelius to develop a new system of notation that could portray the composition of any compound both qualitatively (by showing its electrochemically opposing ingredients) and quantitatively (by showing the proportions in which the ingredients were united).
