Explanation:
Generally, ionic bonds form between a metal and a nonmetal.
Generally, covalent bonds form between two nonmetals.
Generally, metallic bonds form between two metals.
Nonmetals are located on the right side of the periodic table (apart from the noble gases in the final column). Hydrogen is also a nonmetal. Metals are every other element in the periodic table.
A.) Hydrogen (nonmetal) and carbon (nonmetal) = covalent
B.) Aluminum (metal) and magnesium (metal) = metallic
C.) Silicon (nonmetal) and chlorine (nonmetal) = covalent
D.) Magnesium (metal) and sulphur (nonmetal) = ionic
