Atomic Radius - GRE Subject Test: Chemistry - Varsity Tutors

WebAs shown in Figure 3.31, as we move across a period from left to right, we generally find that each element has a smaller covalent radius than the element preceding it.This might seem counterintuitive because it implies that atoms with more electrons have a smaller atomic radius. This can be explained with the concept of effective nuclear charge, Z eff. WebIncrease in Protons and Electrons. One of the most intuitive explanations for the increase in atomic radius down a group is the increase in the number of protons and electrons for atoms in lower groups.
