The positive ionic radius is smaller than the neutral atomic radius
Generally, any element with a lower atomic number.
Smaller
Atoms increase in size as you go down a column and are larger going from right to left across a row.because while going from left to right in a period electrons enter in the same orbit and hence the attraction between the nucleus increasees

Phosphorus has larger ionic radius than sulfur. There is more nuclear attraction in sulfur.

Ionic radius is greater than atomic radius in a negative ion and less than it in a positive ion.
(Chlorine, Fluorine, anything that gains an electron when it ionizes) For example: when F becomes F−, it gains one electron but has the same number of protons, meaning the attraction of the protons to the electrons is weaker, creating a larger radius.
anions always gain extra electrons casing the ionic radius to increase but cations remove electrons causing the ionic radius to decrease .therefore anionic radius is greater than cationic radius
I would not think so as their natural state radius is so close. Ca(2+) loses two electrons, so I think it would have the smaller ionic radius.

Phosphorus (1.23 Å) has an atomic radius smaller than that of tellurium (1.42 Å).
