Question

ionic radius of anion is larger than the atomic radius . why?​

Answer 1

Explanation:

One such trend is closely linked to atomic radii -- ionic radii. Neutral atoms tend to increase in size down a group and decrease across a period. When a neutral atom gains or loses an electron, creating an anion or cation, the atom's radius increases or decreases, respectively.

Answer 2

Answer:

this is because this creates a larger positive charge in the nucleus than the negative charge in the electron charge,causing the electron cloud to be drawn a little closer to the nucleus as an ion
