112 electrons
moving around a nucleus consisting of 112 protons and 165 neutrons.
What is Copernicium made of?
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.

Which element is UUB?
Ununbium
( IPA: /ˌjuːˈnʌnbiəm/), 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. Element 112 is one of the superheavy elements.
Is copernicium a liquid?
Copernicium is predicted to be a pale silver transition metal that
is liquid or perhaps a gas at room temperature
. Although only a few atoms of Copernicium have ever existed, it is predicted to be very dense. … The most stable isotope, copernicium-285, has an observed half-life of 29 seconds.
What atom is GA?
Gallium
is a chemical element with symbol Ga and atomic number 31. Classified as a post-transition metal, Gallium is a solid at room temperature.
Is BR a bromine?
Bromine
is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour.
Why was Copernicium made?
Word origin: Copernicium is
named for Nicolaus Copernicus
, the famed astronomer and mathematician. The symbol Cp was initially recommended for element 112, but was rejected because Cp had once been used as the symbol for lutetium, which, prior to 1949, was sometimes called cassiopeium. … They produced atoms of
277
Cn.
Is Nihonium radioactive?
Nihonium 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. The element, No. 113 on the Periodic Table of Elements, had previously been designated ununtrium, a placeholder name that means one-one-three in Latin.
Is americium synthetic or natural?
Americium, a silvery-white,
synthetic element
, is created during nuclear reactions of heavy elements. The element and its isotopes have very few but important uses including smoke detectors found in nearly all buildings and the potential to power future space missions.
Is Livermorium a natural element?
Livermorium is a synthetic chemical element with the symbol Lv and has an atomic number of 116. It is an extremely radioactive element that has only been created in the laboratory and
has not been observed in nature
.
