Molybdenum. The metal is silvery white, very hard transition metal, but is softer and more ductile than discovered it in 1778. It was often confused with graphite and lead ore. It has a high elastic modulus, and only tungsten and tantalum, of the more readily available metals, have higher melting has one of the highest melting points of all pure elements.
