What type of element is ununoctium?
non-metal
It is expected to be a gas and is classified as a non-metal. It is a member of the noble gas group. The element, No. 118 on the Periodic Table of Elements, had previously been designated ununoctium, a placeholder name that means one-one-eight in Latin.
Is ununoctium a noble gas?
Chemistry. Ununoctium has all its electrons in a closed shell which makes it a member of the noble gas group. Therefore it is most likely that it will have similar properties as other members of the group, resembling in its chemical properties the noble gas above it in the periodic table, radon.
What are some properties of oganesson?

What is a chemical property of ununoctium?
It is probably the second radioactive gaseous element and the first standard semiconductive gas. Ignoring nuclear instability due to radioactivity, scientists expect that ununoctium is much more chemically reactive than xenon or radon. It would likely form stable oxides (UuoO3, etc.) as well as chlorides and fluorides.
How is ununoctium used?
Presently, there are no uses or applications except that it is used for research. Biological use of it is yet to be known. Test Your Knowledge On Ununoctium!
What is the atomic mass of ununoctium?
294 uOganesson / Atomic mass
Are ununoctium and oganesson the same?
The two elements were synthesized by a team of American and Russian scientists and named after the sites of their discovery. And Element 118, previously known as ununoctium, will be named oganesson (Og).
How do you make Ununoctium?
Ununoctium is produced by bombarding atoms of californium-249 with ions of calcium-48 for 11 hours. This production process accumulates a total dose of 2.5 x 1019 calcium ions.
What does oganesson decay into?
livermorium-290
Oganesson’s most stable isotope, oganesson-294, has a half-life of about 0.89 milliseconds. It decays into livermorium-290 through alpha decay.
What is the atomic number of ununoctium?
118Oganesson / Atomic number
What state is ununoctium at room temperature?
The element has an atomic weight of 294 and is solid at room temperature. There is only one isotope, Uuo-294, which is unstable and has a very short half life.
How was ununoctium created?
