Which two elements have almost same electron affinity values?
Correct answer: B. Cl, Br
- A. F, Cl
- B. Cl, Br
- C. F, Br
- D. Br, I
Explanation
The correct answer is Option B: Cl, Br. Chlorine and bromine have electron affinity values of approximately -349 kJ/mol and -324 kJ/mol, respectively. These values are closer to each other compared to the other pairs listed. Option A (F, Cl) and Option C (F, Br) have greater differences in electron affinity. Option D (Br, I) also shows a significant difference in electron affinity values.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
