The Swedish chemist Jöns Jacob Berzelius (1779-1848) was one of the first European scientists to accept John Dalton's atomic theory and to recognize the need for a new system of chemical symbols. He was a dominant figure in chemical science. 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 method by which one or two letters are used to symbolize the elements.

Berzelius tried to reduce the selenium salts to the pure metal in different ways, but found it difficult to obtain it in a pure enough form for an atomic weight determination. The impurities, mainly mercury, copper, tin, lead, zinc, arsenic, and iron were difficult to remove.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. 2017-11-30 Jöns Jacob Berzelius, Linköping, Swed, Stockholm, modern chemistry, atomic weights, modern chemical symbols, electrochemical theory, classical analytical techniques Download this stock image: Jons Jacob Berzelius (1779-1848), Swedish chemist who introduced modern chemical symbols.
