History

History
The element Sodium was discovered by Humphry Davy in year 1807 in United Kingdom. Sodium derived its name from from the English word soda (natrium in Latin)
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
