I dont see why it isnt 19 A vertical column in the periodic table. However, when William Wollaston analysed the minerals from which it had been extracted he declared it was identical to niobium which has been discovered the year previously. The boom in mobile electronics means that tantalum is now more in demand, and probably more widely known than at any point since it was discovered in 1802.
