History

History
The element Chromium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Chromium derived its name from from the Greek word chroma, meaning 'color'
The element Lead was discovered by Middle East in year 4000 BC in unknown place. Lead derived its name derived its name from from English word (plumbum in Latin)
