Ununquadium (Uuq)

Science / Periodic Table of Elements / Ununquadium (Uuq): Atomic number: 114, Atomic mass: 289 g.mol -1, Electronegativity acoording to Pauling: unknown, Density: unknown, Melting point: unknown, Boiling point: unknown, Vanderwaals radius: unknown, Ionic radius: unknown, Isotopes: unknown, Discovered: Dubna (Joint Institute for Nuclear Research) in Russia, jan 1999. It is expected to have properties similar to those of lead and tin. Ununquadium can be synthesized by bombarding plutonium 244 targets with calcium 48 heavy beams. Applications: Ununquadium does not have any known application and little is known about it. Ununquadium in the environment: Ununquadium does not occur naturally on the earth, it is entirely synthesized in laboratories. Health effects of ununquadium: As it is so unstable, any amount formed would decompose to other elements so quickly that there’s no reason to study its effects on human health. Environmental effects of ununquadium: Due to its extremely short half-life (about 21 seconds), there’s no reason for considering the effects of ununquadium in the environment.
