tungsten

Wolfram W

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.
