History

History
The element Chlorine was discovered by Carl Wilhelm Scheele in year 1774 in Sweden. Chlorine derived its name from from the Greek word chloros, meaning 'greenish yellow'
The element Tellurium was discovered by Franz-Joseph Müller von Reichenstein in year 1783 in Romania. Tellurium derived its name derived its name from from Latin tellus, meaning 'earth'
