FTP, who was this Swedish chemist, the discoveror of the elements thorium, selenium, and cerium?
This chemist coined the terms protein, allotropy, isomerism, and halogen, was the first to isolate zirconium, and proposed the system of chemical symbols and formulae now in use. By his observations of platinum's behaviour during some reactions he postulated catalysis, and he was able to estallish the validity of Proust's law of definite proportions and Dalton's atomic theory with the 2,000 relative atomic and molecular masses he determined.
