History
| Parameter | Boron | Antimony |
|---|---|---|
| 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 Antimony was discovered by Arabic alchemist in year ca. 800 AD in one. Antimony derived its name from the Greek anti, 'against', and monos, 'alone' (stibium in Latin). |
