History

History
The element Nobelium was discovered by Joint Institute for Nuclear Research in year 1958 in Sweden and United States. Nobelium derived its name from from Alfred Nobel, chemist, engineer, innovator, and armaments manufacturer
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
