History

ParameterGoldCalcium
HistoryThe element Gold was discovered by Bulgaria in year Before 6000 BCE. Gold derived its name from English word (aurum in Latin).The element Calcium was discovered by H. Davy in year 1808 in United Kingdom. Calcium derived its name from the Latin calx, meaning 'lime'.
