Cn

Background

Copernicium was discovered on 9 February 1996 by a group of research scientists working at the Heavy Ion Research Laboratory in Darmstadt, Germany under the guidance of Sigurd Hofmann. The new element was named after mathematician and astronomer Nicolaus Copernicus.

Isotopes

Related Stories

Copernicium is said to have five isotopes whose half-lives are known with mass numbers from 277 to 285. All five are unstable. However copernicium-285, is the most stable isotope with a half-life of 34 sec. It decays into darmstadtium-281 through alpha decay.

Production

Scientists bombarded lead-208 nuclei with zinc-70 nuclei in a heavy ion accelerator, which resulted in a single atom of copernicium-277.

Health Aspects

Copernicium is considered to be harmful due to its radioactive nature. However it has not been properly researched to provide specific details regarding its health effects.

Key Properties

Copernicium is a synthetic radioactive metal.

Applications

Currently, copernicium has no applications outside the realm of scientific research.
