Overview
Nihonium is a synthetic element created to investigate chemical periodicity and nuclear stability in the region beyond the actinides.
Properties
Limited experimental data suggest possible +1 and +3 oxidation states; relativistic effects strongly influence its chemistry.
Occurrence and Uses
No practical applications; produced in minute quantities for fundamental research in nuclear chemistry and atomic physics.
Isotopes and Safety
Nihonium isotopes are radioactive and extremely short lived; experiments require remote handling, containment and radiological safeguards.
