Description

Standard State: Presumably a solid at 298 K
Color: Unknown, but probably metallic and silvery white or gray in appearance

Element 112 was discovered on 9th February 1996 at 22:37 at the GSI in Darmstadt, Germany.

As only a few atoms of element 112 have ever been made (through a nuclear reaction involving fusing a zinc atom with a lead atom) isolation of an observable quantity has never been achieved, and may well never be.
