History

History
The element Niobium was discovered by Charles Hatchett in year 1801 in United Kingdom. Niobium derived its name from from Niobe, daughter of king Tantalus from Greek mythology
The element Potassium was discovered by Humphry Davy in year 1807 in United Kingdom. Potassium derived its name derived its name from from New Latin potassa, 'potash' (kalium in Latin)
