History

History
The element Copper was discovered by Middle East in year 8000 BC in unknown place. Copper derived its name from from English word (Latin cuprum)
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)
