History

History
The element Actinium was discovered by Friedrich Oskar Giesel in year 1899 in France. Actinium derived its name from from the Greek aktis, 'ray'
The element Chlorine was discovered by Carl Wilhelm Scheele in year 1774 in Sweden. Chlorine derived its name derived its name from from the Greek word chloros, meaning 'greenish yellow'
