History

History
The element Aluminium was discovered by in year 1825 in Denmark. Aluminium derived its name from from alumina, a compound (originally aluminum)
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')
