History

ParameterGoldPotassium
HistoryThe element Gold was discovered by Bulgaria in year Before 6000 BCE. Gold derived its name from English word (aurum in Latin).The element Potassium was discovered by H. Davy in year 1807 in United Kingdom. Potassium derived its name from New Latin potassa, 'potash' (kalium in Latin).
