Chemical & Physical Characteristics
- It's a highly radioactive metal
- Only few atoms of it have ever been made
- It's really only ever used in research
- To produce it, element 115 - Moscovium - must first be made. Through alpha decay, nihonium can be made
- It has 6 isotopes with known half lives; the most stable of which has a half life of 20 seconds
- Not much else is known about the element since it is so new
Nihonium
Element
History:
- Element 113 was previously a placeholder known as Ununtrium (meaning one-one-three in latin)
- Scientists at the RIKEN Nishina Center for Accelerator-based Science (Japan) managed to create the element for the first time in July of 2004. They did this by accelerating zinc ions up to 10 percent of the speed of light (c = 3x10^8m/s) and then impacting them onto a thin bismuth target. Upon a series of alpha decays, dubnium-262 was formed, which then became the first atom of Nihonium via spontaneous fission.
- The name Nihonium in japanese means "land of the rising sun"
Thank you!
