Mattia CarroccioI was looking again at the periodic trends like Ionization Energy, Electron Affinity, Radius and so on. I understood all the general trends and the exeptions for these ones, but I can't fully understand the trends for Atomization Enthalpy/Energy. Quoting my book ( Inorganic Chemistry - Atkins ) : "...

Q: PVP-iodine and octenidine can stain skin purple, does the reaction create iodine radicals?

Michael PaulIn this paper it is mentioned that ... octenidine can release iodine radicals from the PVP complex, resulting in a tissue irritation as well as strong brown to violet discolouration in the border areas. but elsewhere I read that ... it turns out that ΔG > 0 for radical iodination. Is it reall...
