Question

Ionic radius of f- is more than atomic radius of f give reason

Answer 1

$\sf{F_2}$ is converted into $\sf{F_2^{-}}$ after gaining and electron. Now, there is an extra electron, so shielding effect increases and effective nuclear charge decreases. Due to which, the size of anion increases. Hence, size of anion is more than its parent atom.

Answer 2

Answer:

Explanation:

After gaining electron, repulsion increases and so ionic radius also increases...!
