The increase in the size of an anion is due to an increase in the repulsion of?
Correct answer: B. Electron-electron
- A. Electron-proton
- B. Electron-electron
- C. Electron-nucleus
- D. Proton-nucleus
Explanation
The increase in size of an anion is due to the increase in the repulsion of electrons. As the number of electrons increases, they start to repel each other more strongly, causing the size of the anion to increase.

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.
