Text Solution

AI Generated Solution

To classify the given substances into ionic, covalent, molecular, or metallic, we will analyze each substance based on their bonding characteristics. ### Step-by-Step Solution: 1. **MgO (Magnesium Oxide)**: - **Classification**: Ionic - **Explanation**: MgO is formed from the transfer of electrons from magnesium (Mg) to oxygen (O), resulting in the formation of Mg²⁺ and O²⁻ ions. The electrostatic attraction between these oppositely charged ions constitutes ionic bonding. ...
