Paradoxes and paradigms: elements and compounds: similar names, very different energetics. Part 5, selected examples of exotic species and isotopes (H, He, C, F, U). Struct Chem (2023). https://doi.org/10.1007/s11224-023-02208-xhttps://doi.org/10.1007/s11224-023-02208-xhttp://hdl.handle.net/11603/29533In this paper we continue to review the phonetic similarity of trivial names of chemical substances, in the particular, the names of isotopes of selected elements (H, He, C, F, U) of the periodic table. Thermochemical properties are explicitly considered.10 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
