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, and devised the modern […] Jöns Jakob Berzelius. SWEDISH CHEMIST 1779–1848 Before the early 1800s the symbols used to denote chemical elements and compounds were obscure.

Although Berzelius began his career as a physician, his enduring Jons Jacob Berzelius was a Swedish chemist born on August 20, 1779 – died on August 07, 1848. Berzelius was best known for his determination of atomic weights, chemical notation, isolation and discovery of silicon, selenium, thorium and cerium periodic table elements. He is known as "the Father of Swedish Chemistry". 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.

His law established inorganic substances to bond together to form definite proportions by weight. 2019-02-28 His work in the transuranic elements led to a reconfiguration of the periodic table where he placed the actinide series below the lanthanide series at the bottom of the table, to give the periodic table the look it has today.
