The elements that do not have quoted ionic radii are the noble gases. These elements do not form ionic compounds and therefore there is no crystallographic data.
All of the other elements have ionic radii, these are either an "estimate" from the apparent size of the ion in different compounds, or a calculated value.
Ionic radius is a useful idea but it should not be taken to literally, comparatively few compounds are truly ionic, most of them have some covalent character.
The best examples of elements where the ionic radius is meaningful are the group 1, 2 metals, oxide ion and the lighter halogens.

What elements have the smallest ionic radius k o s li?
Li+
Which element has the largest radius?
francium has the largest ionic radius
Why elements and all compound exist as molecules?
All elements and all compounds do not exist as molecules. As examples, noble gases exist as individulal atoms and ionic compounds form lattices.
Why are group 8A elements not represented by ionic radius?
they will become another element if they loose or gain 8 electrons
What elements have an ionic radius equal to the atomic radius?
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.

What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius
What is the definition of ionic radius?
The ionic radius is the measure of an atom's ion in a crystal lattice. The value for an ionic radius is typically 30 pm to about 200 pm. An ionic radius is usually measured using x-ray crystallography.

What are the factors affecting lattice energy?
ionic charge and ionic radius; the smaller the ionic radius the greater the lattice energy
What is the ionic radius of sodium?
The ionic radius of sodium ion is 0.095 nm while its covalent radius is 0.157 nm.
How does ionic radius differ from atomic radius?
Ionic radius is greater than atomic radius in a negative ion and less than it in a positive ion.
