SUMMARY
The discussion centers on the search for electron affinities greater than one for iodine (I), carbon (C), and hydrogen (H). It is established that such electron affinities do not exist for these atoms in the gas phase, as even oxygen, which can form a dianion (O2-), does so in a highly endothermic manner, making it unstable. The reference article provided offers insights into the rare existence of dianions, emphasizing the difficulty of binding two additional electrons.
