- Copernicium is a synthetic chemical element with symbol Cn and atomic number 112 in the periodic table.
- It was first created at Gesellschaft fur Schwerin enforcing in the year 1996. The element is named after the astronomer Nicolaus Copernicus who formulated a heliocentric model with planets revolving around the sun.
- It is highly radioactive and the synthetic element which is not found in nature but can be synthesized in the laboratory.
- In the periodic table, Copernicium is a d-block transactinide element and belongs to group 12 elements.
- It is predicted to be in a gaseous state at normal temperature and pressure.
- When reacted with gold, this element showed to be an extremely volatile metal.
- It does not have any stable or naturally-occurring isotopes.
- Many radioactive isotopes have been created in the lab, either by observing decay of heavier metals or by fusing two elements.
- Six different isotopes have been identified with Atomic mass numbers 277, 281 to 285.
- Presently, it does not have any uses or applications, except being used in the research. As it is not found in nature, there is no chance of being affected by it.
- Copernicium is produced by bombarding lead for two weeks with zinc traveling at 30,000 km per second.
- Isotope-277 had a half-life of 0.24 milliseconds.
