Answer:
C.) Molecular compounds are composed of two or more nonmetals.
Explanation:
A.) is incorrect. Ionic compounds are composed of metal(s) and nonmetal(s). The metal forms the cation and the nonmetal forms the anion. When two metals combine, they create a metallic compound and experience metallic bonding.
B.) is incorrect. Organic compounds are always molecular compounds because they only contain covalent bonds.
C.) is correct. Molecular compounds must be made of two nonmetals and experience covalent bonding. Should a nonmetal and metal come together, they would form an ionic compound and experience ionic bonding.
D.) is incorrect. Organic compounds are always made up of carbon atoms covalently bonded to other atoms, usually hydrogen or other carbon atoms. Therefore, organic compounds do not always contain hydrogen or oxygen.
