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 Arsenic was discovered by Bronze Age in year 1250 in unknown place. Arsenic derived its name derived its name from English word (Latin arsenicum)
