WebJan 2, 2024 · Thus nuclear charge increases and screening effect increases. Hence there is decreases in the atomic radius but the extent of variation is very small compared to s block and p block elements. The extent of variation is so small that all of them can be considered to have almost equal atomic radii. Share Improve this answer Follow WebElectropositive nature of an element increases down the group because the effective nuclear charge decreases and the atomic size increases down the group, so because of the addition of new shells to the atom the attraction of the valence electrons to the nucleus decreases due to large distance between them . ion mobility in different buffer gas https://acebodyworx2020.com
