History
| Parameter | Dysprosium | Gold |
|---|---|---|
| History | The element Dysprosium was discovered by P.E.L. de Boisbaudran in year 1886 in France. Dysprosium derived its name from the Greek dysprositos, meaning 'hard to get'. | The element Gold was discovered by Bulgaria in year Before 6000 BCE. Gold derived its name from English word (aurum in Latin). |
