"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
