Elements and compounds are more similar to each other than they are to mixtures because:
elements and compounds cannot be reduced to simpler substances by physical or mechanical means, but mixtures can
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
