Vedclass · Answer

(D) The ionic radius depends on the effective nuclear charge and the number of shells. For ions of the same element,the radius decreases as the positive charge increases because the remaining electrons are pulled more strongly by the nucleus. Comparing $P^{+3}$ and $P^{+5}$,$P^{+3}$ has more electrons than $P^{+5}$,resulting in greater electron-electron repulsion and a larger ionic radius. Therefore,$P^{+3} > P^{+5}$ is the correct relationship.
