He also developed a table of atomic weights. 1829 - Johann Wolfgang Dobereiner discovered some elements had similar chemical properties. 1865 - John Newlands arranged the known elements in order of atomic weight and was able to see patterns. •Historically, the development of the periodic table was based on the classification of elements according to their chemical and physical properties.
Berzelius developed the radical theory of chemical combination, which holds that reactions occur as stable groups of atoms called radicals are exchanged between molecules. He believed that salts are compounds of an acid and bases, and discovered that the anions in acids would be attracted to a positive electrode, whereas the cations in a base would be attracted to a negative electrode.

The Episodic Table of Elements. A chemistry podcast about the fascinating true stories behind each element on the periodic table. Lived 1779 – 1848. 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 Jacob Berzelius Biography - Swedish chemist Pantheon
Berzelius was a Swedish chemist. In 1828 he compiled a table of relative atomic weights, where oxygen was set to 100, and which included all of the elements known at the time. Of significance for the periodic table is that he invented the modern system of chemical notation and established the basic symbols for the elements as used today. Periodic Table.
