History

History
The element Rhenium was discovered by Masataka Ogawa in year 1925 in Germany. Rhenium derived its name from from Rhenus, the Latin name for the river Rhine
The element Niobium was discovered by Charles Hatchett in year 1801 in United Kingdom. Niobium derived its name derived its name from from Niobe, daughter of king Tantalus from Greek mythology
