Question

Why cations are smaller and anions are bigger in their neutral atoms

Answer 1

Answer:

cation are the atoms or molecules which have lost one or more electron

Explanation:

therfore due to loose of electron cation is smaller than Parent atom and the addition of electron

always result in anion

that are larger than parent atom this is your answer

Answer 2

Answer:

Cation are smaller & anions larger in radii than their parent atoms because there is a loss of electrons from valence shell in the case of cation ,so decreases the shell number and in the case of anion there is addition of electrons. which cause decreases in size of cation and increases the size of anion.
