History
| 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 Boron was discovered by L. Gay-Lussac and L.J. Thénard in year 1808 in France and United Kingdom. Boron derived its name from borax, a mineral. |
