The negative ionic radius is larger than the neutral atomic radius
Ionic radius is the size of an ion after it has gained or lost electrons, leading to a change in the electron configuration and thus its size. Atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outermost electron shell. Ionic radius is affected by the change in electron configuration, while atomic radius is more related to the position of the outer electrons in the neutral atom.
the positive ionic radius is smaller than the neutral atomic radius
The fluoride ion is larger than the fluoride atom because it has gained an extra electron, resulting in an increase in electron-electron repulsions, which causes the electron cloud to expand. This increase in electron-electron repulsions leads to a larger ionic radius compared to the atomic radius of the fluoride atom.
Potassium has a larger atomic radius than sodium. This is because as you move down a group in the periodic table, atomic size generally increases due to additional electron shells being added, leading to increased electron-electron repulsion and a larger atomic radius.
in the case of non-metals, the anions are formed by the addition of electrons. So the ionic radius is larger than that of the atomic radius
The negative ionic radius is larger than the neutral atomic radius
When an atom loses an electron, it typically becomes a positively charged ion (cation). This loss of an electron results in a reduction of electron-electron repulsion in the electron cloud, which allows the remaining electrons to be drawn closer to the nucleus. As a consequence, the atomic radius decreases. Thus, the atomic radius of an atom decreases when it loses an electron.

Na atom has a higher atomic radius compared to Na+ ion. This is because Na+ ion has lost an electron, leading to a decrease in electron-electron repulsion and a smaller electron cloud, causing the ion to have a smaller atomic radius than the neutral Na atom.
Potassium has a larger atomic radius than sodium. This is because as you move down a group in the periodic table, atomic size generally increases due to additional electron shells being added, leading to increased electron-electron repulsion and a larger atomic radius.
The relation between electron affinity and atomic radius is inversely proportional.
in the case of non-metals, the anions are formed by the addition of electrons. So the ionic radius is larger than that of the atomic radius
Bromine's atomic radii is larger than that of chlorine.
When an anion forms, its atomic radius increases. This occurs because the addition of one or more electrons to the atom increases electron-electron repulsion within the electron cloud, causing the cloud to expand. As a result, the overall size of the ion becomes larger than that of the neutral atom.
The atomic radius decreases.
