History

History
The element Tantalum was discovered by Anders Gustaf Ekeberg in year 1802 in Sweden. Tantalum derived its name from from King Tantalus, father of Niobe from Greek mythology
The element Rhodium was discovered by William Hyde Wollaston in year 1803 in United Kingdom. Rhodium derived its name derived its name from from the Greek rhodos, meaning 'rose coloured'
