"WebYes because Fe 3+ has one less electron the nuclear charge acting on electrons is larger and electronic repulsion is lesser. This causes the outer shell of Fe 3+ to be pulled a little more inwards compared to Fe 2+. Hence it’s size is smaller. And in general cations are smaller than anions. As for why atomic radii decreases rightwards is because although … " - Ionic radii of fe

Oxidation of … WebIf electrons are added to the atom, the ion becomes larger. The ionic radius for an atom is measured in a crystal lattice , requiring a solid form for the compound. These radii will differ somewhat depending upon the technique used. Usually X-ray crystallography is employed to determine the radius for an ion. Figure 1.

WebHis studies found that crystal structures obey the following rules, now known as Pauling's Rules. Rule 1. Around every cation, a coordination polyhedron of anions forms, in which the cation-anion distance is determined by the radius sums and the coordination number is determined by the radius ratio.
