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 Platinum was discovered by A. de Ulloa in year 1748 in Peru. Platinum derived its name from the Spanish platina, meaning 'little silver'. |
