History
| Parameter | Lead | Dysprosium |
|---|---|---|
| History | The element Lead was discovered by Africans in year 7000 BCE. Lead derived its name from English word (plumbum in Latin). | 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'. |
