History

History
The element Beryllium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Beryllium derived its name from from beryl, a mineral
The element Calcium was discovered by Humphry Davy in year 1808 in United Kingdom. Calcium derived its name derived its name from from the Latin calx, meaning 'lime'
