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 Iodine was discovered by Bernard Courtois in year 1811 in France. Iodine derived its name derived its name from from French iode (after the Greek ioeides, 'violet')
