What is Copernicium?

  • 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.

Physical properties of Copernicium

  • 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.

Applications and effects of Copernicium

  • 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.

Certain Facts About Copernicium

  • 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.
