Element 118 has atomic configuration of 7s2 7p6 , so it is an nobel gas.

Understanding Element 118
Element 118, known as Oganesson (Og), is a synthetic element with significant characteristics.
Classification of Oganesson
- Noble Gas: Oganesson is classified as a noble gas, which is a group in Group 18 of the periodic table.
- Properties of Noble Gases: Noble gases are known for their lack of chemical reactivity, due to having a complete valence shell of electrons. However, as we explore Oganesson, it exhibits some unique properties that may differ from other noble gases.
Why Not Alkali, Lanthanide, or Transition Elements?
- Not Alkali Metals: Alkali metals (Group 1) are highly reactive and have only one electron in their outer shell, unlike the full valence shell in noble gases.
- Not Lanthanides: Lanthanides are a series of 15 elements from lanthanum to lutetium found in the f-block of the periodic table. Oganesson does not fall within this series.
- Not Transition Elements: Transition elements are found in the d-block and are characterized by partially filled d-subshells. Oganesson, being a p-block element, does not belong to this category.
Conclusion
In summary, element 118 is categorized as a noble gas due to its position in the periodic table and its electronic configuration. Oganesson holds a unique position and may exhibit atypical behavior compared to other noble gases, but it retains the fundamental classification as a noble gas.
