3.1: Molecular Compounds - Chemistry LibreTexts
In general, the elements that coine to form binary molecular compounds are both nonmetals. This contrasts with ionic compounds, which involve bonds between metal ions and nonmetal anions. One difference between ionic and molecular compounds is that two nonmetal atoms will frequently coine with one another in a variety of ratios.
