First isolated in 1782 by  Peter Jacob Hjelm, its main use is in alloys, such as with iron and  steel, to which it adds hardenability and strength at high  temperatures.
Roughly as abundant as tungsten, which it resembles, this  element is not found free in nature. First isolated in 1782 by  Peter Jacob Hjelm, its main use is in alloys, such as with iron and  steel, to which it adds hardenability and strength at high  temperatures. Its excellent corrosion resistance makes it useful in  electric and electronic parts, and in the chromium trim on  automobiles and bicycles. FTP, name this element with atomic number  42 whose chemical symbol is Mo.
