Explain why cations are smaller and anions larger in radii than their parent atoms?
A cation has a fewer quantity of electrons than its figure atom, even as its nuclear rate stays the same. As a result, the appeal of electrons to the nucleus is extra in a cation than in its discern atom. Therefore, a cation is smaller in length than its figure atom. On the alternative hand, an anion has one or greater electrons than its determine atom, ensuing in an improved repulsion the various electrons and a lower withinside the powerful nuclear price. As a result, the space among the valence electrons and the nucleus is greater in anions than in it is the figure atom. Hence, an anion is greater in radius than its determine atom.
