According to Encyclopedia Britannica in Britannica School the word tungsten comes from the mineral scheelite which was once called tungsten, which means heavy stone. The name comes from the Swedish chemist and his countrymen who discovered the metal in scheelite. The atomic number of tungsten is 74 and tungsten’s atomic weight is 183.84. Tungsten is also one of the densest and hardest metals in the world. From Encyclopedia Britannica in Britannica School, tungsten was discovered by a Swedish chemist named Carl Wilhelm Scheele who discovered tungsten oxide in scheelite, while two brothers, the Spanish chemists Fausto and Juan Jose de Elhuyar used wolframite to prepare the first sample of tungsten metal. Tungsten was discovered in 1781 but

Tungsten is made by heating up crystals that are found in scheelite which produce tungsten trioxide, which is then heated with hydrogen at 850 degrees celsius which produces tungsten. Tungsten’s most common form is scheelite which was the first mineral that had tungsten trioxide. Tungsten is very abundant most tungsten production come from China which it is then put on the tips of mining drills. In Encyclopedia Britannica in Britannica School, tungsten has five stable isotopes, tungsten-180, tungsten-182, tungsten-183, tungsten-184, and tungsten-186. There is no radioactive isotope in tungsten that decays into anything. It belongs to group VI-B on the periodic table.
In Facts on File in Science Online, pure tungsten is used in light bulbs and x-rays, while others are used in the production of extremely hard steel for tools, sometimes called tungsten steels. It is also used in the tips of mining drills.
From Facts on File in Science Online, tungsten is in chemical compounds such as sodium tungstate. Tungsten is also in chemical compounds to flameproof cloth. Tungsten has no health effects, as it is used in drills. Tungsten also has no known positive or negative effects on any person or animal that comes in contact with
