History

History
The element Boron was discovered by Joseph Louis Gay-Lussac in year 1808 in France and United Kingdom. Boron derived its name from from borax, a mineral
The element Bromine was discovered by Antoine Jérôme Balard in year 1826 in France. Bromine derived its name derived its name from from the Greek bromos, meaning 'stench'
