History

History
The element Beryllium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Beryllium derived its name from from beryl, a mineral
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')
