Heaviest Element Officially Named Copernicium

The heaviest element yet known is now officially named "Copernicium," after the astronomer Nicolaus Copernicus.

Copernicum has the atomic number 112 — this number denotes the number of protons in the nucleus of an atom. It is 277 times heavier than hydrogen, making it the heaviest element officially recognized by international union for chemistry IUPAC.

The name for the element was suggested by the team that discovered it, led by Sigurd Hofmann at the GSI Helmholtzzentrum für Schwerionenforschung in Germany.

The suggested name "Copernicium" in honor of Nicolaus Copernicus (1473-1543) follows the tradition of naming chemical elements after merited scientists. IUPAC officially announced the endorsement of the new element's name on Feb. 19, Nicolaus Copernicus' birthday. Copernicus' work in the field of astronomy is the basis for our modern, heliocentric world view, which states that the Sun is the center of our solar system with the Earth and all the other planets (in our solar system) circling around it.

On the periodic table of elements, Copernicium will have the symbol "Cn." The team had originally suggested "Cp" as the element's symbol, but because this abbreviation has other uses in science (such as a material's specific heat), the team agreed to "Cn."
