please be more specific and I might be able to answer this correctly
The radius decreases, particularly if the entire complement of valence electrons in the neutral atom is missing from the positive ion.
it gets smaller.
smaller
Atoms gain electrons and form negative charged ions and become larger. Increased distance= larger radius. On the periodic table, the left is the smaller positive ions. The right side is the larger negative ions.
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
a general answer is that if it is a cation the ion is smaller than the atom due to loosing one or more electrons which would decrease the size of the radius anions are larger because they are gaining more electrons and electron electron repulsion is greater which spreads the anion apart
The same quantity of a charge and the opposite sign.
The larger the highest energy level, the larger the atomic radius.

It becomes an ion with a larger radius than the atom of chlorine
The positive ionic radius is smaller than the neutral atomic radius
The negative ionic radius is larger than the neutral atomic radius
Elements become larger in atomic radius because they have an increased number of electrons, which increases the level of shielding, which causes the nuclear influence to become less strong on the outer level of electrons allowing them to space farther apart.
Protons have a larger mass, but it is unclear which (if either) have a larger radius. The electron does not seem to have ANY measurable radius.

When there is an anion (negative charge) the radius will be larger because it is more full whereas it will be smaller if it is a positive charge because of less electrons. ex largest to smallest radius (K-,K, K+)
The smaller to the larger is a ratio of 6:10 or 3:5
Because the metal loses an electron (making it smaller) and the non metal gains that electron, making it larger.
