Summary
His interest in all sorts of compounds led to his discovery of a number of new elements, including cerium, selenium, and thorium. Students working in his laboratory also discovered lithium, vanadium, and several rare earths. Using his experimental results, he determined the atomic weights of nearly all the elements then known. Dealing with so many elements in so many compounds motivated his creation of a simple and logical system of symbols—H, O, C, Ca, Cl, and so forth—which is basically the same as the system we use today He also discovered some elements Silicon, Saylean, Thorium, and cerium. He also created the law of Definite proportions.
