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

WebApr 9, 2024 · Basically, the atomic number is the same as the number of protons in the nucleus. For example, the atomic number of lithium is 3, and also the number of protons in the nucleus of lithium is 3. So, yes, the atomic number of an element is directly proportional to the effective nuclear charge, if you look at it from this point of view. I hope this ... WebSep 28, 2024 · The size increase because the effective nuclear charge (positive charge of nucleus) experienced by the outer electrons decreases down a group. Effective nuclear charge decreases because the inner electrons repel the outer electrons, weakening the nucleus pull for the outer electrons.
