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 Boron was discovered by Joseph Louis Gay-Lussac in year 1808 in France and United Kingdom. Boron derived its name derived its name from from borax, a mineral |
