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.

Why do some elements not have a value for ionic radius?
Some elements do not have a well-defined ionic radius because their ions may have varying charge states or coordination environments which affect their size. Additionally, experimental challenges in measuring the ionic radii of certain elements may also contribute to the lack of precise data for these elements.
What is the ionic radius for xenon?
The ionic radius of xenon is not commonly reported as it is a noble gas and typically does not form ions in chemical compounds. Xenon tends to exist in its elemental form as a monatomic gas.
Is Li have the smallest ionic radius?
No, H+ ions are the smallest (proton size), hydrogen atoms and even Li+ ions are smaller than Li atoms.
Which element has the largest radius?
francium has the largest ionic radius
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 has the smalled ionic radius?
The Hydrogen Ion has the smallest ionic radius.
What is the ionic radius of copper?
The ionic radius of copper can vary depending on its oxidation state. For example, the ionic radius of Cu2+ is approximately 73 pm, while the ionic radius of Cu+ is around 77 pm.
Why doesn't neon have an ionic radius?
Neon does not have an ionic radius because it does not readily form ions. Neon is a noble gas with a full outer electron shell, making it very stable and unlikely to gain or lose electrons to form ions. Therefore, it does not have a defined ionic radius like other elements that can form ions.
What is the ionic radius of aluminum?
The ionic radius of aluminum is approximately 0.54 angstroms.
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.
Pauling ionic radius pm of sodium?
The Pauling ionic radius of the sodium ion is 95.
What are the factors affecting lattice energy?
ionic charge and ionic radius; the smaller the ionic radius the greater the lattice energy
