History
| Parameter | Actinium | Tungsten |
|---|---|---|
| History | The element Actinium was discovered by F. O. Giesel in year 1902 in France. Actinium derived its name from the Greek aktis, 'ray'. | The element Tungsten was discovered by W. Scheele in year 1781 in Spain. Tungsten derived its name from the Swedish tung sten, 'heavy stone' (W is wolfram, the old name of the tungsten mineral wolframite). |
