Elements and compounds are more similar to each other than they are to mixtures because:

elements and compounds can only be liquids or solids, but mixtures can be solids, liquids or gases


elements and compounds can be homogeneous or heterogeneous, but mixtures can only be heterogeneous


elements and compounds do not have fixed melting points, but mixtures do
