Copernicium is a synthetic chemical element; it has symbol Cn and atomic number 112. Its known isotopes are extremely radioactive, and have only been created in a laboratory. The most stable known isotope, copernicium-285, has a half-life of approximately 30 seconds.

鿔是第112号化学元素，于1996年被合成出来，被正式命名为“Copernicium”，符号为Cn，中文译名为“鿔”。 此名称是为了纪念著名天文学家哥白尼（Copernicus）而得名的。

Copernicium is a man-made element of which only a few atoms have ever been made. It is formed by fusing lead and zinc atoms in a heavy ion accelerator.

Copernicium. Copernicium is a chemical element with symbol Cn and atomic number 112. Classified as a transition metal, Copernicium is a expected to be a solid at room temperature.

Copernicium (Cn), artificially produced transuranium element of atomic number 112. In 1996 scientists at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung [GSI]) in Darmstadt, Ger., announced the production of atoms of …

Copernicium is considered as one of the most highly radioactive element. It can react with gold and exhibit a highly volatile behavior. Copernicium is resistant to oxidation and requires specific conditions for its oxidation unlike the other members of its group.

2013年11月20日 · Copernicium is a radioactive, synthetic element about which little is known. It is classified as a metal and is expected to be solid at room temperature.

2021年5月7日 · Copernicium atom is a zinc group element atom with a symbol Cn and atomic number 112. All its isotopes are intensely radioactive. Prior to its discovery, it had the placeholder name ununbium (in accordance with IUPAC recommendations). Following its discovery (in Darmstadt, 1996) and subsequent confirmation, the name copernicium was adopted in 2010.
