Question Analysis
This question involves the judgment of chemical bond types based on the types of bonded elements.

Key Concept Explanation
Ionic bonding occurs when electrons are transferred from one atom to another. The atom that loses electrons becomes a cation (positively charged), while the atom that gains electrons becomes an anion (negatively charged). The ionic bond is the electrostatic attraction between these oppositely charged ions.

Step-by-step Solution
1. Identify the elements involved: Magnesium (Mg) is a metal (loses electrons) and oxygen (O) is a nonmetal (gains electrons).
2. ...
