Tungsten (also called wolfram) [14] [15] is a chemical element; it has symbol W and atomic number 74. It is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a distinct element in 1781 and first isolated as a metal in 1783.

2025年1月9日 · tungsten (W), chemical element, an exceptionally strong refractory metal of Group 6 (VIb) of the periodic table, used in steels to increase hardness and strength and in lamp filaments.

Today, tungsten is primarily obtained from wolframite and scheelite (CaWO 4) using the same basic method developed by José and Elhuyar. Tungsten ores are crushed, cleaned and treated with alkalis to form tungsten trioxide (WO 3).

Tungsten is a chemical element of the periodic table with chemical symbol W and atomic number 74 with an atomic weight of 183.841 u and is classed as transition metal and is part of group 6 (chromium group). Tungsten is solid at room temperature.

Tungsten is the 74th element in the periodic table and has a symbol of W and atomic number of 74. It has an atomic weight of 183.84 and a mass number of 184. Tungsten has seventy-four protons and one hundred ten neutrons in its nucleus, and seventy-four electrons in six shells.

Pure tungsten is a steel-gray to tin-white metal. Tungsten has the highest melting point and lowest vapour pressure of all metals, and at temperatures over 1650°C has the highest tensile strength. The metal oxidises in air and must be protected at elevated temperatures.

Tungsten was discovered in 1783, it is also known as wolfram as it is an exceptionally strong metal. It has the highest melting and boiling points and alloys of tungsten are used in various high-temperature applications.
