Tungsten Element Introduction
Tungsten (atomic symbol: W, atomic number: 74) is a Block D, Group 6, Period 6 element with an atomic weight of 183.84. The number of electrons in each of tungsten's shells is [2, 8, 18, 32, 12, 2] and its electron configuration is [Xe] 4f14 5d4 6s2. Tungsten Bohr ModelThe tungsten atom has a radius of 139 pm and a Van der Waals radius of 210 pm. Tungsten was discovered by Torbern Bergman in 1781 and was first isolated by Juan José Elhuyar and Fausto Elhuyar in 1783. In its elemental form, tungsten has a grayish-white, lustrous appearance. Elemental TungstenTungsten has the highest melting point of all metallic elements and a density comparable to that of uranium or gold and about 1.7 times that of lead. Tungsten alloys are often used to make filaments and targets of X-ray tubes. It is found in the minerals scheelite (CaWO4) and wolframite [(Fe,Mn)WO4].
