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 Samarium was discovered by Lecoq de Boisbaudran in year 1879 in France. Samarium derived its name derived its name from from Samarskite, the name of the mineral from which it was first isolated |
