History

History
The element Dysprosium was discovered by Lecoq de Boisbaudran in year 1886 in France. Dysprosium derived its name from from the Greek dysprositos, meaning 'hard to get'
The element Terbium was discovered by Carl Gustaf Mosander in year 1843 in Sweden. Terbium derived its name derived its name from from Ytterby, Sweden
