Webb18 nov. 2024 · 1. Table shows some physical properties of Group 18 elements. 2. Atomic radius (atomic size) The atomic radii (atomic sizes) of noble gases increase when going down Group 18 from helium to radon. This is because the number of shells occupied with electrons increases when going down the group. 3. Webbgroup, in chemistry, a column in the periodic table of the chemical elements. In a group, the chemical elements have atoms with identical valence electron counts and identical valence vacancy counts. This similarity in both the composition and structure of their atomic valence shells implies a corresponding similarity in both their chemical and physical …
