History
Name | Boron | Barium |
History | The element Boron was discovered by L. Gay-Lussac and L.J. Thénard in year 1808 in France and United Kingdom. Boron derived its name from borax, a mineral. | The element Barium was discovered by W. Scheele in year 1772 in United Kingdom. Barium derived its name from the Greek barys, meaning 'heavy'. |
