History

History
The element Tungsten was discovered by Carl Wilhelm Scheele in year 1783 in Spain. Tungsten derived its name from from the Swedish tung sten, 'heavy stone' (W is wolfram, the old name of the tungsten mineral wolframite)
The element Niobium was discovered by Charles Hatchett in year 1801 in United Kingdom. Niobium derived its name derived its name from from Niobe, daughter of king Tantalus from Greek mythology
