Question

Do u knw the answer of why cations are always smaller than its parental atom???

Answer 1

cations are smaller than their parent atoms . The opposite is true of negative ions. When electrons are added to form an anion,the increased electron-electron repulsion cause the electrons to spread out more in space. Thus,anions are larger than their parent atoms.

hope it helps

Answer 2

cations are smaller than parental atom bcz cations are formed after lose of electron due to which shielding effect decreases
