History

History
The element Phosphorus was discovered by Hennig Brand in year 1669 in Germany. Phosphorus derived its name from from the Greek word phoosphoros, 'carrying light'
The element Mendelevium was discovered by Lawrence Berkeley National Laboratory in year 1955 in United States. Mendelevium derived its name derived its name from from Dmitri Mendeleev, chemist and inventor
