Question

Which of the following statements are correct?

a) F is the most electronegative and Cs is the most electropositive element
b) The electronegativity of halogens decreases from F to I
c) Electron affinity of Cl is higher than that of F whereas their electronegativities are in reverse order
d) Electron affinity of noble gases is almost zero

Strategy:
 Review core halogen properties () and group trends ().

Step 1: Evaluate each statement
- (a): Fluorine () is the most electronegative (), and Cesium is the most electropositive (lowest stable ). (Correct)
- (b): Electronegativity decreases down Group 17 as size increases. (Correct)
- (c): Electron affinity of Chlorine () is more negative than Fluorine () due to Fluorine's small size and  repulsion. However, Fluorine remains more electronegative. (Correct)
- (d): Noble gases have stab
