History

History
The element Carbon was discovered by Ancient Egypt in year N/A in unknown place. Carbon derived its name from the Latin word carbo, meaning 'coal'
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)
