Answer:
Correct Answer: 34. (electronegativity)
Solution:
- Statement I is true; Statement II is false. $F$ 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 $F$ than by $3 p$-electrons in $Cl$-atom.
