Discovery of Copernicium

Copernicium was first made by research scientists led by Sigurd Hofmann at the Heavy Ion Research Laboratory in Darmstadt, Germany in 1996.

Scientists bombarded lead-208 nuclei with zinc-70 nuclei in a heavy ion accelerator.

A single atom of copernicium-277 resulted from the bombardment.

Atoms of copernicium-281, copernicium-281 and copernicium-284 have been recorded more recently as decay products of flerovium.

The element is named after astronomer and mathematician Nicolaus Copernicus.

Appearance and Characteristics

Harmful effects:

Copernicium is harmful due to its radioactivity.


Copernicium is a synthetic radioactive metal and has only been produced in minute amounts.

Uses of Copernicium

Copernicium is of research interest only.

Abundance and Isotopes

Abundance earth’s crust: nil

Abundance solar system: parts per billion by weight, parts per trillion by moles

Cost, pure: $ per 100g

Cost, bulk: $ per 100g

Source: Copernicium is a synthetic radioactive metal, created via nuclear bombardment, and has only been produced in minute amounts. Copernicium is produced by bombarding 208Pb with 70Zn in a heavy ion accelerator.

Isotopes: Copernicium has 5 isotopes whose half-lives are known with mass numbers from 277 to 285. None are stable. The most stable isotope is 285Cn, with a half-life of 34 seconds.
