History
History |
The element Antimony was discovered by unknown in year 3000 BC in unknown place. Antimony derived its name from from the Greek anti, 'against', and monos, 'alone' (stibium in Latin) |
The element Calcium was discovered by Humphry Davy in year 1808 in United Kingdom. Calcium derived its name derived its name from from the Latin calx, meaning 'lime' |
