WebHelium is not truly a member of Group 18 (or Group VIII in the older system). We just place it there because it is unique and does not really fit into any group. It is placed there because it is practically inert, like the other noble gases. Not all elements follow the octet rule. H, He, Li, and Be never follow the Octet Rule. Web25 jan. 2024 · Group 18 Elements: The noble gases (Group \(18\)), which are found at the far right of the periodic table, were originally known as “inert gases” because of their filled valence shells (octets), which make them exceedingly nonreactive. In comparison to other element groupings, noble gases were discovered comparatively late. Henry Cavendish, …
