Step-by-step explanation:

• An ionic compound is formed as a result of an ionic bond between a nonmetal ion and metal ion.
• Ionic bonds are forces of attraction that occur between nonmetal atoms and metal atoms.
• The metal atom loses an electron(s) to form a cation and a non-metal atom gains electron(s) to form an anion.
• An ionic compound is formed as a result of the electrostatic force of attraction between the negatively charged ion(anion) and the positively charged ion(cation).
• For example, sodium fluoride(NaF) is an ionic compound between Na⁺ (cation) and F⁻(anion).
• Other examples of ionic compounds include NaCl, CaBr₂, KF, MgCl₂, etc.
