(B) When an atom loses one or more electrons to form a cation,the number of protons remains the same,but the number of electrons decreases. This results in an increased effective nuclear charge,which leads to a stronger electrostatic attraction between the nucleus and the remaining electrons,pulling them closer and causing the ionic radius to be smaller than the atomic radius.
