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.

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).

Symbol: Uub Atomic Number: 112 Atomic Mass: (277.0) amu Melting Point: Unknown Boiling Point: Unknown Number of Protons/Electrons: 112 Number of Neutrons: 165 Classification: Transition Metal Crystal Structure: Unknown Density @ 293 K: Unknown Color: Unknown More information about the naming of the heavy elements is available. Atomic Structure

the strong relativistic 7s contraction and the relativistic 6d expansion, the 7s electrons of Uub are more deeply bound than the 6d5/2 electrons, which results in the marked difference of the atomic structure between Uub and Hg. We have also compared the properties of Uub+ and Uub 2+with Hg+ and Hg .Table1

Uub is a highly unstable element with a half-life of just a few milliseconds. This means that it rapidly decays into lighter elements through a process known as alpha decay. Because of its short half-life, Uub has no practical applications and is primarily of interest to scientists studying the properties of the heaviest elements.

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.

Definition of Uub. Uub is a synthetic element, meaning that it is not found naturally on Earth and must be created in a laboratory through nuclear reactions. It has an atomic number of 112, which means that it has 112 protons in its nucleus. Its symbol on the periodic table is Cn.

Uub has an atomic number of 112, which means it has 112 protons and 112 electrons. Uub is a transition metal, which means it belongs to the same group as other metals such as copper, silver, and gold. Its atomic weight is 285 u, and it has a density of around 23.7 g/cm3.
