Jöns Jacob Berzelius

Jöns Jacob Berzelius was a Swedish chemist in the early 19th century who is often regarded as one of the founders of modern chemistry. He introduced a system of chemical notation that uses symbols for elements, allowing chemists to represent compounds clearly. Berzelius also made significant contributions to understanding chemical bonding and the properties of inorganic substances. His work helped establish the basis for stoichiometry, the study of the proportions of elements in chemical reactions, greatly advancing both inorganic chemistry and analytical techniques that are still in use today.
