Tungsten - Wikipedia. Tungsten (also called wolfram) [10] [11] is a chemical element; it has symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783.
اقرأ أكثرMaterials with strong bonds between atoms will have a high melting temperature. However, other factors--such as crystal structure, atomic weight, and electron structure--can also influence the melting point. Tungsten, rhenium, osmium, tantalum, and molybdenum are among the highest melting point metals.
