Copernicium is a synthetic element with the symbol Cn and atomic number 112. It was first created in 1996 by a team of scientists at the GSI Helmholtz Centre for Heavy Ion Research in Germany. This element is named after the astronomer Nicolaus Copernicus, who proposed the heliocentric model of the solar system. As a member of the d-block in the periodic table, Copernicium is classified as a transition metal. It is highly unstable, with a half-life of only a few milliseconds, making it difficult to study. Due to its short-lived nature, Copernicium has no significant commercial applications and is primarily of interest for scientific research.
