History
Name | Osmium | Sulfur |
History | The element Osmium was discovered by S. Tennant in year 1803 in United Kingdom. Osmium derived its name from the Greek osmè, meaning 'smell'. | 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'. |
