History
| Parameter | Nihonium | Silicon |
|---|---|---|
| History | The element Nihonium was discovered by K. Morita et al.(RIKENin Wako, Japan) in year 2004 in Russia and United States. Nihonium derived its name from the Japanese name for Japan, Nihon, where the element was first synthesized. | The element Silicon was discovered by J. Berzelius in year 1823 in Sweden. Silicon derived its name from the Latin silex, 'flint' (originally silicium). |
