What is Oganesson?
Oganesson is a radioactive, man-made element about which little is known. It is categorized as a non-metal and is predicted to be a gas. It belongs to the category of noble gases. Oganesson is categorized as a super-heavy element because it contains a total of 176 Neutrons and 118 Electrons constituting an atomic mass of 294. Moreover, the number of protons in the nuclei is 104.
Oganesson was created by bombarding the californium atoms with calcium ions for 1,080 hours. Three oganesson atoms were produced as a result of this intense bombardment.
Discovery Of The Element 118
Russian researchers at the Joint Institute for Nuclear Research in Dubna, Russia, made Oganesson their first official discovery in 2002. A study announcing the discovery of element 118 was released three years earlier, in 1999, by a team from the Lawrence Berkeley Labs in California. However, the team's findings could not be verified, and they subsequently withdrew their paper. The Lawrence Livermore National Laboratory team and the Dubna team, who had been collaborating with the Dubna scientists, officially declared the element in 2006.
Nomenclature Of Oganesson
The element was once known as ununoctium, a placeholder name that stands for one-one-eight in Latin and is listed as element 118 on the Periodic Table of Elements. The name oganesson for element 118 was authorized by the International Union of Pure and Applied Chemistry (IUPAC) in November 2016.
According to IUPAC representatives, the name oganesson pays homage to Yuri Oganessian "for his significant contributions to transactinide elements research," which refers to elements having atomic numbers 104 through 120.

Electronic Configuration Of Oganesson
Since all of the shells of Oganesson are completely filled, the element with atomic number 118 will be grouped with the noble gases in group 18 and possesses the Electronic Configuration: 1s2 2s2 2p6 3s22 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6
Reduced Electronic Configuration: [Rn] 7s2 7p65f14 6d10.
Isotopes Of Oganesson
With a half-life of roughly 0.89 milliseconds, Oganesson has only one isotope that is known to be the most stable ²⁹⁴Og (oganesson-294). It becomes ²⁹⁰Lv (livermorium-290) through alpha decay. The rate of radioactive decay of the isotope- oganesson-294 is given as: ²⁴⁹₉₈Cf + ⁴⁸₂₀Ca → ²⁹⁴₁₁₈Og +3n
Properties Of Oganesson
Oganesson hasn't been generated in sufficient amounts to be properly studied. On theoretical calculations and computational techniques, all of the physical and chemical predictions are predicated.
Oganesson is predicted to have a boiling point between 320 K and 380 K, making it liquid at room temperature in contrast to other noble gases.
It may be a viable semiconductor, according to more studies.
Uses Of Oganesson
A few oganesson atoms have been created, however other than scientific research, it has no practical applications.
Interesting Facts About Oganesson
This element is artificial, therefore its properties are unknown, however, it is thought to be a noble gas.
One living person, Yuri Oganessian, is honored by having his name placed on just one element at the moment.
Of the 25 elements, oganesson is one of them that has not yet been seen in a crystal structure.
Less than 6 oganesson atoms have been found in studies worldwide since 2005.
Of all known elements, oganesson presently has the greatest atomic mass number (118).
Oganesson is an atomic number 118 chemical element with the symbol Og. Oganesson is a noble gas that is anticipated to be a gas at room temperature. This is an artificially created element that does not exist in nature. Because of its extreme radioactivity, this element can only be created for a short moment (less than a second) before radioactive decay occurs.
Oganesson has only ever been used for scientific purposes; nothing else. In a similar vein, since scientists have only been able to create a little amount of oganesson, it is unable to speculate on its potential impacts on health.

1. What is the essence of Oganesson Og?
2. What are the uses of oganesson?
3. Which group elements are called noble gases?
The groups of elements called noble gases are odourless and colourless elements, and they don’t have a specific taste and are highly inflammable. The gases are traditionally labelled as group O as part of the periodic table because, for years, it was believed that they were not able to get attached to the other atoms. These are atoms that cannot combine with the rest of the elements in forming the chemical compounds. The element has a basic electronic structure that can be highly used in the field of research. As a member of the group, the element of oganesson is quite rare.
4. What is the source of Element 118?
The source of Oganesson is Californium-249 atoms which were ionized with calcium-48 ions to create the element ununoctium. Some seasoned Scientists oversaw this process. Three free neutrons and the isotope ununoctium-294, with a half-life of around 0.89 milliseconds (0.00089 seconds), were created during this operation. The californium target was exposed to a total of 1.6 x 1019 calcium ions during the finding of ununoctium. Over 1080 hours were needed to finish this operation. Three ununoctium atoms result from this reaction.
5. How many possible stable isotopes of Oganesson are known to exist?
Only one isotope of oganesson 294-Og, having a half-life of roughly 0.89 milliseconds, is currently known to be stable. It has been successfully synthesized by scientists out of the eight potential heavy-ion fusion processes. The theoretical result states that there are eight distinct isotopes of oganesson. The isotope 295 Og, which has not been verified yet has a half-life of 181 milliseconds as recorded in 2011. Many studies are being conducted to look for these isotopes globally as there were only three atoms synthesized so far.
6. What is unique about Oganesson?
The largest atomic mass and an atomic number of any known element are found in oganesson. Being the first synthetic element and a member of group 18 (the noble gases), it is more reactive than all the other members of that group. Under ordinary situations, it was formerly believed to be a gas, however, relativistic factors have led to the prediction that it will really be solid. In addition to being significantly more reactive than radon, it may even be more reactive than the heavier counterparts of the more chemically active elements Pb, Hg, flerovium, and copernicium, respectively.
