History

History
The element Copper was discovered by Middle East in year 8000 BC in unknown place. Copper derived its name from from English word (Latin cuprum)
The element Chromium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Chromium derived its name derived its name from from the Greek word chroma, meaning 'color'
