Berzelius (Jöns Jacob Berzelius)

Jöns Jacob Berzelius was a Swedish chemist born in 1779 who made groundbreaking contributions to modern chemistry. He is best known for developing a system of chemical symbols—like H for hydrogen and O for oxygen—that are still used today. Berzelius also identified and studied many chemical elements, helping to organize the periodic table. His work improved the understanding of atomic weights and chemical compounds, advancing the scientific study of chemistry. Overall, Berzelius's discoveries helped standardize how chemists communicate and analyze materials, laying a foundation for modern chemical science.
