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 Neptunium was discovered by Edwin McMillan in year 1940 in United States. Neptunium derived its name derived its name from from Neptune, the eighth planet in the Solar System
