In context|organic chemistry|lang=en terms the difference between superatom and heptaphane

is that superatom is (organic chemistry) one or more atoms of a basic structure that are replaced by amplificants in the amplification process of phane nomenclature while heptaphane is (organic chemistry) in the nomenclature of complex organic compounds, any linear phane containing seven nodes (or superatoms).

As nouns the difference between superatom and heptaphane

is that superatom is (physics|chemistry) a cluster of atoms which seems to exhibit some of the properties of elemental atoms while heptaphane is (organic chemistry) in the nomenclature of complex organic compounds, any linear phane containing seven nodes (or superatoms).
