History

History
The element Lithium was discovered by Johan August Arfwedson in year 1817 in Sweden. Lithium derived its name from the Greek word lithos, meaning 'stone'
The element Tantalum was discovered by Anders Gustaf Ekeberg in year 1802 in Sweden. Tantalum derived its name derived its name from from King Tantalus, father of Niobe from Greek mythology
