History
| Parameter | Helium | Sulfur |
|---|---|---|
| History | The element Helium was discovered by P. Janssen and N. Lockyer in year 1868 in Sweden and United Kingdom. Helium derived its name from the Greek word helios, meaning 'sun'. | 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'. |
