Tungsten has a melting point of over 3000 degrees and is therefore used, among other things, as a filament in lamps. (The name of the company Osram, which manufactures light bulbs, among other things, is derived from the elements osmium and tungsten.). As one of the few elements in the periodic table, its German name is completely different than in the English-speaking world, where tungsten is known as Tungsten. This name is derived from Swedish (tung sten = heavy stone). Here you can find some properties about tungsten and where the element got its name from. And at ChemistryViews there is a poem about Wolfram in addition to various information. There's also a short video below that introduces the element.
The 6th group of the periodic table contains the elements chromium, molybdenum, tungsten and the rather exotic seaborgium, which does not occur in nature. The group is also called the chromium group after the lightest member. All elements are metals and often occur in the oxidation states +2, +3 and +6). All elements of this group are used, among other things, for alloys.
