Cation and Anions

Why are cations smaller than their parents atoms, and anions larger than their parent atoms?

Cations are smaller than their parent ions since an electron is removed to form the cation. Because electrons primarily make up the volume of an atom, the cation will be smaller since it has fewer electrons. Anions are larger than their parent atoms because an electron is gained to form an anion, therefore, increasing the number of electrons and the size.
