Question

Which of the following is correct with respect to size? [ ]

A. Atom < Anion< Cation C. Anion<Atom<Cation

B. Cation < Atom < Anion D. Cation < Anion< Atom​

Answer 1

$\sf\underline{Answer:}$

Option B ; Anion has the greatest size

$\sf\underline{Explanation:}$

As proton number is more than electrons, the nucleus of the cation attracts outer shell electrons with stronger force that's why the size shrinks and anion has the lower size than the neutral atom. It is the opposite of this in the cation.
