History
| Parameter | Iodine | Hassium |
|---|---|---|
| History | The element Iodine was discovered by B. Courtois in year 1811 in France. Iodine derived its name from French iode (after the Greek ioeides, 'violet'). | The element Hassium was discovered by G. Münzenberg, P. Armbruster et al.(GSI in Darmstadt) in year 1984 in Germany. Hassium derived its name from Hesse, Germany, where the element was first synthesized. |
