Second and higher electron affinity values are positive because of:
Correct answer: A. Repulsion between electrons and negatively charged ions
- A. Repulsion between electrons and negatively charged ions
- B. Attraction between electrons and positively charged ions
- C. First repulsion between electrons and then attraction
- D. Both A and B
Explanation
Second and higher electron affinity values are positive because adding an additional electron to an already negatively charged ion (anion) is energetically unfavorable.When you try to add another electron to an already negatively charged ion, it becomes increasingly difficult. The additional electron experiences a strong electrostatic repulsion from the negatively charged ion, making the process energetically unfavorable.

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.
