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 Tellurium was discovered by Franz-Joseph Müller von Reichenstein in year 1783 in Romania. Tellurium derived its name derived its name from from Latin tellus, meaning 'earth'
