In 1979, IUPAC published recommendations according to which the element was to be called ununbium (with the corresponding symbol of Uub), [63] a systematic element name as a placeholder, until the element was discovered (and the discovery then confirmed) and a permanent name was decided on.

2017年3月13日 · Get periodic table facts on the chemical and physical properties of the element ununbium, which has been named copernicium.

Copernicium (formerly Ununbium) is a chemical element in the Periodic Table. It is also named eka -mercury. It has the symbol Cn. It has the atomic number 112. It is a transuranium element. The element is named in honor of Nicolaus Copernicus. Using periodic trends, people think that it will be a liquid metal like mercury.

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.

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 from fusing zinc -70 with lead …

Copernicium (pronounced as kogh-per-NEE-see-em), previously known as ununbium, is a synthetic element, denoted by the symbol Cn [1, 3].

Ununbium (pronounced /juːˈnʌnbiəm/), or eka-mercury, is a temporary IUPAC systematic element name for a chemical element in the periodic table that has the temporary symbol Uub and the atomic number 112.

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. Its properties are somewhat similar to...

Unlike element 110, Copernicium has properties more similar to radon than mercury, but due to its short half-life, it is difficult to study. As of 2011, Copernicum's most stable isotope has an atomic weight of 285.

Copernicium (Ununbium, Uub) - chemical symbol Cn, atomic number 112 - is the proposed name of the synthetic, superheavy chemical element no 112. Online available information resources about the chemistry and physics of Copernicium, Cn
