Answer:
Correct Answer: 30.(electronegativity)
Solution:
- Statement I is true; Statement II is false. $\mathrm{F}$ atom has slightly lower affinity for the electron than chlorine. It is due to the reason that additional electrons are repelled more effectively by $2 p$-electrons in $\mathrm{F}$ than by $3 p$-electrons in $\mathrm{Cl}$-atom.
