Question

explain why cations are smaller and anions larger in radii than thrir parent atoms?​

Answer 1

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. ... Cations are always smaller than their parent atoms this is because they have lesser electrons, while their nuclear charge remains the same.

Answer 2

Answer:

due to loss of electron

Explanation:

Cations donate electrons whereas anions accept the electrons

as their is more number of protons , the nucleus pulls the electrons closer than their parent atoms

hence they r smaller in size
