element 114

Scientific  

1. An artificially produced radioactive element whose most stable isotope has a mass number of 289 and a half-life of approximately 2.7 seconds. Radioactive decay of all isotopes is chiefly by alpha-particle transmission.

2. Also called ununquadium

3. See Periodic Table
