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. Named after the astronomer Nicolaus Copernicus, it is classified as a transactinide element and is part of the group 10 elements in the periodic table. Due to its short half-life, copernicium is highly unstable and has no significant commercial applications. It is primarily used for research purposes in nuclear chemistry and physics. The most stable isotope, Cn-285, has a half-life of about 29 seconds.
