Calcium oxide is formed as a result of transfer of _ valence electrons.
Correct answer: B. two
- A. one
- B. two
- C. three
- D. four
Explanation
It i clear from this reaction , two electrons are transfered to oxygen to form CaO. Valence shell of Ca has 2 electrons that it loses forming Ca+2 and these electrons gained by O-2 , these both ions bind forming calcium oxide.

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.
