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 Selenium was discovered by Jöns Jakob Berzelius in year 1817 in Sweden. Selenium derived its name derived its name from from the Greek selene, meaning 'moon'
