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 … Web13 apr. 2024 · We have studied the insulator-to-metal transition and crystal structure evolution under high pressure in the van der Waals compound CoPS 3 through in situ electrical resistance, Hall resistance, magnetoresistance, x-ray diffraction, and Raman scattering measurements.
