The correct symbol for Tungsten is W. Tungsten is a chemical element with the atomic number 74 and atomic weight 183.84. It is a transition metal and has the highest melting point of all known elements. Tungsten is commonly used in electrical applications, such as light bulb filaments and electrical contacts, due to its high thermal and electrical conductivity. Its symbol W comes from its previous German name "Wolfram".
