Tarihi
Carl Jacob Löwig discovered bromine in 1825, while still a chemistry student at Heidelberg University, Germany.
Antoine Balard distilled the bromine from a solution of seaweed ash saturated with chlorine in 1824.
He finally published his results in 1826, providing evidence that the substance he had discovered was a new element.
