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.
Cancer is one of the twelve constellations of the zodiac and is located in the Northern celestial hemisphere.Its name is Latin for crab and it is commonly represented as one. . Cancer is a medium-size constellation with an area of 506 square degrees and its stars are rather faint, its brightest star Beta Cancri having an apparent magnitude of 3
55 Cancri is a binary star system located 41 [1] light-years away from the Sun in the zodiac constellation of Cancer.It has the Bayer designation Rho 1 Cancri (ρ 1 Cancri); 55 Cancri is the Flamsteed designation (abbreviated 55 Cnc).
55 Cancri b is in a short-period orbit, though not so extreme as that of the previously detected hot Jupiter 51 Pegasi b.The orbital period indicates that the planet is located close to a 1:3 mean motion resonance with 55 Cancri c, however investigations of the planetary parameters in a Newtonian simulation indicate that while the orbital periods are close to this ratio, the planets are not ...
Breast cancer is one of the most common forms of cancer for women, with 300,000 Americans diagnosed this year alone. While this may sound like a scary statistic, the odds are in our favor. Thanks ...
The heaviest known group 12 element, copernicium, was first created on February 9, 1996, at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany, by Sigurd Hofmann, Victor Ninov et al. [61] It was then officially named by the International Union of Pure and Applied Chemistry (IUPAC) after Nicolaus Copernicus on February 19 ...
He was the leading scientist with the discovery experiments of the chemical elements darmstadtium (Ds, atomic number 110), [2] roentgenium (Rg, 111) [3] and copernicium (Cn, 112). [4] He made substantial contributions to the discovery experiments of the elements bohrium ( Bh , 107), [ 5 ] hassium ( Hs , 108) [ 6 ] and meitnerium ( Mt , 109). [ 7 ]
Copernicium-285 has only been observed as a decay product of flerovium-289 and livermorium-293; during the first recorded synthesis of flerovium, one flerovium-289 was created, which alpha decayed to copernicium-285, which itself emitted an alpha particle in 29 seconds, releasing 9.15 or 9.03 MeV.
