Down the groups of the periodic table, the removal of electrons from the valence shell is easy due to:
Correct answer: B. Addition of Shells
- A. Addition of Electrons
- B. Addition of Shells
- C. Increase in Nuclear Charge
- D. Strong Attractive Forces
Explanation
When you go down in groups in periodic table, the removal of electron become easy because as we go down the number of shells increases hence the nuclear attraction to the electron weakens.

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.
