The positive ionic radius is smaller than the neutral atomic radius
Generally, any element with a lower atomic number.
Fluorine has an ion, specifically the fluoride ion (F⁻), that is smaller than a calcium ion (Ca²⁺). The fluoride ion has a negative charge, which increases its electron cloud size, but its atomic radius is still smaller than that of the calcium ion, which has lost two electrons and has a higher positive charge. Consequently, the increased nuclear charge in Ca²⁺ pulls the remaining electrons closer, resulting in a smaller ionic radius compared to that of F⁻.
Smaller
Potassium has a larger ionic radius than sulfur.
Examples are: Be, Al, Ti, V, Mn, Co, Ni etc.
Phosphorus has larger ionic radius than sulfur. There is more nuclear attraction in sulfur.

An element that has a larger ionic radius than calcium is strontium. Strontium is located below calcium in the same group of the periodic table, which means it has an extra energy level and therefore a larger ionic radius.
The ionic radius of Mg2 is smaller than that of other ions in the same group on the periodic table.
a) Sc,Ti,V,Crb) Na,K,Rb,Csc) B,Si,As,Ted) F,Cl,Br,Ie) Na,Mg,Al,SiThe correct answer of these options is a) Sc,Ti,V,Cr because they are the closest elements to each other in the periodic table.
No, H+ ions are the smallest (proton size), hydrogen atoms and even Li+ ions are smaller than Li atoms.
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.
