Question

Why are cations smaller and anions larger in radii than their parent atom?

Answer 1

Cations are always smaller than their parent atoms this is because they have lesser electrons, while their nuclear charge remains the same. The remaining electrons are, therefore held more tightly by the protons in the nucleus and thus their radii.are smaller than the parent atoms. This is opposite in case of anions.

Answer 2

Answer:

Cations are smaller in size because they are formed by loss of electrons and anions are larger in size because they are formed by the gain of electrons.

The remaining electrons are, therefore held more tightly by the protons in the nucleus and thus their radii. are smaller than the parent atoms.
