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 Einsteinium was discovered by Lawrence Berkeley National Laboratory in year 1952 in United States. Einsteinium derived its name derived its name from from Albert Einstein, physicist
