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 Potassium was discovered by Humphry Davy in year 1807 in United Kingdom. Potassium derived its name derived its name from from New Latin potassa, 'potash' (kalium in Latin)
