According to the research, the molecules of compound are combinations of chemical elements of different complexity, while the molecules of element are made up of atoms of the same type.
The molecules of compound are a mixture, its elements can have any proportion interrelated by chemical bonds and maintain their properties, while the molecules of element is the set of atoms of the same type that cannot be broken down into simpler ones.
The molecules of compound and an element have a fixed and defined chemical composition, belonging to pure substances, where all the particles, atoms, molecules and/or elements that compose it are exactly the same.
Therefore, we can conclude that according to the research, the molecules of compound are combinations of chemical elements of different complexity, while the molecules of element are made up of atoms of the same type.
