However, there is a special material which is twice as dense as lead. Assuming that it is a natural material existing on earth, osmium (chemical symbol Os) is the densest and heaviest metal! It is a metallic chemical element in the platinum family.This blue-grey material is hard but fragile. Also, it is extremely rare. It is usually used to make pen points, phonograph needles, and instrument pivots.How much does it weigh? A liter of osmium weighs 22.6 kg. How heavy! An average small car weighs about 1,540 kg. To our surprise, only 0.056 cubic meters of osmium weigh the same! It is around the same volume as a paper grocery bag. Therefore, if you had a piece of osmium about the size of a paper grocery bag, it would weigh as much as a new car! 답변자 ts0068 답변일 2015-02-05 답변내용 Maybe lead popped into your mind. *CORRECT!
