What Uuo 118?
Ununoctium (symbol Uuo, number 118) is a synthetic, super heavy, transactinide element, also known as element 118 and eka-radon. Ununoctium is the temporary IUPAC name. These elements have atomic numbers from 104 to 118. They are also transuranium elements and are artificially produced.

What are the properties of element 119?
Element 119 is expected to be a typical alkali metal with a +1 oxidation state. The energetic properties of its valence electron, the 8s electron, suggest that its first ionization potential will be higher than the oxidation potential predicted by simple extrapolation, so that the…
What is the heaviest element known to man?
uranium
The heaviest naturally stable element is uranium, but over the years physicists have used accelerators to synthesize larger, heavier elements. In 2006, physicists in the United States and Russia created element 118.
What are the facts about the element 118?
Facts About Oganesson (Element 118) In November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name oganesson for element 118. The IUPAC also approved names for elements 113 ( nihonium, with atomic symbol Nh), 115 ( moscovium, Mc) and 117 ( tennessine, Ts).

Facts About Oganesson (Element 118) Oganesson is a radioactive, artificially produced element about which little is known. It is expected to be a gas and is classified as a non-metal.
What is the atomic number of oganesson ununoctium?
Oganesson Ununoctium is a transactinide chemical element with symbol Uuo and atomic number 118. It was first created by a joint team of American and Russian scientists at the Joint Institute for Nuclear Research in Dubna, Russia. Ununoctium is a temporary name and the suggested name is Oganesson which may be formally accepted by the end of 2016.
Why is element 118 considered a volatile liquid?
In a 1975 article, American chemist Kenneth Pitzer suggested that element 118 should be a gas or volatile liquid due to relativistic effects. In late 1998, Polish physicist Robert Smolańczuk published calculations on the fusion of atomic nuclei towards the synthesis of superheavy atoms, including oganesson.
