History
| Parameter | Germanium | Flerovium |
|---|---|---|
| History | The element Germanium was discovered by C. A. Winkler in year 1886 in Germany. Germanium derived its name from Germania, the Latin name for Germany. | The element Flerovium was discovered by Yuri Oganessian et al.(JINRinDubna) in year 2004 in Russia. Flerovium derived its name from Flerov Laboratory of Nuclear Reactions, part of JINR where the element was synthesized; itself named for Georgy Flyorov, physicist. |
