The charge on a cation M is +2 & on anion A is -3, the compound formed has formula:
Correct answer: B. M3A2
- A. M2A
- B. M3A2
- C. MA2
- D. M2A3
Explanation
The compound formed has the formula M3A2. The cation M has a charge of +2, and the anion A has a charge of -3. To balance the charges, the compound must have three M cations for every two A anions. This gives the formula M3A2

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.
