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 Dysprosium was discovered by Lecoq de Boisbaudran in year 1886 in France. Dysprosium derived its name derived its name from from the Greek dysprositos, meaning 'hard to get'
