The symbol for Copernicium is Cn. The electron configuration is [Rn] 5f14 6d10 7s2. It only has one use: research. It is a highly radioactive metal that is considered non-reactive. It is considered more of a noble gas than metal. Only a few atoms have ever been made from this. The most stable known isotope has a half-life of approximately 29 seconds. The key isotope is 285 Cn.]]> 2016-12-02 14:32:20 UTC https://padlet.com/johnson_jacob/tyyodabb4tj9/wish/141387348 johnson_jacob https://padlet.com/johnson_jacob/tyyodabb4tj9/wish/141400069 Physical Properties; Atomic mass average is 277.
