History

History
The element Nickel was discovered by Axel Fredrik Cronstedt in year 1751 in Sweden. Nickel derived its name from from Swedish kopparnickel, containing the German word Nickel, 'goblin'
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'
