Notable Characteristics

Element 112 is one of the heaviest known elements and the atoms of the element decompose through the emission of alpha-particles with a half life of only about 240 µs (microseconds).

Uses

• Element 112 has no uses because only a few atoms of Ununbium have been made.

History

On the 9th February 1996 at 22:37 at the GSI in Darmstadt, Germany, Element 112 was discovered. The current name is the IUPAC's tempoary systematic element name.

Precautions

Element 112 does not occur naturally. Altough if enough was created and put in one place it would create a radiation hazard.
