Vedclass · Answer

(D) The size of an atom or ion depends on the effective nuclear charge and the number of electrons.For a given element,the order of size is: Anion $(X^-)$ > Neutral atom $(X)$ > Cation $(X^+)$.This is because an anion has more electrons than protons,leading to increased electron-electron repulsion and a larger size.$A$ cation has fewer electrons than protons,leading to a stronger pull by the nucleus on the remaining electrons,resulting in a smaller size.Therefore,the correct order is $Cl^- > Cl > Cl^+$.

Which of the following is the correct order of size of the given species?
