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'
