History
Name | Sulfur | Rubidium |
History | The element Sulfur was discovered by Chinese/Indians in year Before 2000 BCE. Sulfur derived its name from the Latin word sulphur, 'fire and brimstone'. | The element Rubidium was discovered by R. Bunsen and G. R. Kirchhoff in year 1861 in Germany. Rubidium derived its name from the Latin rubidus, meaning 'deep red'. |
