Is Element 118 possible?
Oganesson is a synthetic chemical element with the symbol Og and atomic number 118. Oganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the isotope oganesson-294 have been detected.
What color is Oganesson?

How do you make Oganesson?
They produced oganesson by bombarding atoms of californium-249 with ions of calcium-48. This produced oganesson-294, an isotope with a half-life of about 0.89 milliseconds (0.00089 seconds), and three free neutrons.
What is Silver’s valency?
Generally the valency of silver is + 1 , as the d sub – shell has stable configuration if they lose 1 electron from s sub – shell . therefore the most common valency of silver is 1 .
Is element 118 a metal or nonmetal?
Oganesson
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. It is a member of the noble gas group.
What are the symbols of the 118 elements?
118 Elements and Their Symbols and Atomic Numbers Name of the Element Symbol of the Element Atomic Number Neon Ne 10 Sodium Na 11 Magnesium Mg 12 Aluminium Al 13
Which is the decay daughter of element 116?
The decay properties of 290116 and 291116, and the dependence of their production cross sections on the excitation energies of the compound nucleus, 293116, have been measured in the 245Cm ( 48Ca, xn) 293−x116 reaction. These isotopes of element 116 are the decay daughters of element 118 isotopes, which are produced via the 249Cf+ 48Ca reaction.
What kind of element is oganesson element 118?
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 excitation energy of element 118?
We performed the element 118 experiment at two projectile energies, corresponding to 297118 compound nucleus excitation energies of E∗ =29.2±2.5 and 34.4±2.3 MeV.
