How is the chemical formula of an ionic compound found?
From the charges on the ions present in the compound
explain Ionic vs Molecular compound
Ionic compounds contain ions of opposite charge held together by the force of attraction between the charges
Molecular compounds contain atoms held together by shared electrons
