Verified step by step guidance

Step 1: Understand the difference between ionic and covalent bonds. Ionic bonds form between metals and nonmetals through the transfer of electrons, while covalent bonds form between nonmetals by sharing electrons.

Step 2: Analyze each compound to identify the types of atoms involved. For example, MgO, KCl, and CaF_2 are composed of metal and nonmetal atoms, which typically form ionic bonds.

Step 3: Look at NaNO_3 (sodium nitrate). It contains Na^+ (a metal cation) and NO_3^- (a polyatomic ion). The bond between Na^+ and NO_3^- is ionic.

Step 4: Within the NO_3^- ion, the nitrogen and oxygen atoms are nonmetals bonded together. These bonds are covalent because they share electrons.

Step 5: Conclude that NaNO_3 contains both ionic bonds (between Na^+ and NO_3^-) and covalent bonds (within the NO_3^- ion), making it the correct answer.
