Molybdenum was discovered by the Swedish chemist Scheele in 1778. In 1782, Hjelin, a chemist of the same school, succeeded in isolating it by using the trioxide for its production. The pure metal is very heavy, silver white in color, and very difficult to fuse. In the air it remains unchanged, and only combines with oxygen when heated to low redness. It takes up carbon, forming alloys, which are more easily fusible, but much harder than the pure metal. 16 p.Additional Links
