Tantalum
· Tantalum was reported as a new metal in 1802 by the Swedish chemist Anders Gustav Ekeberg, who was Professor of Chemistry at Uppsala University. However, when William Wollaston, the eminent British chemist, analysed minerals from which it had been extracted, he declared it was indentical to the new metal niobium which had been discovered the previous year. These two .
