Upon the formation of the 5-FU− anion, 12 different fragmentation products are observed, the most probable dissociation channel being H loss. The parent anion, 5-FU−, is not stable on the …

WebSo, that is part of the issue. Unlike electronegativity, the electron affinity does not have a strong periodic value. The electron affinity measures the energy released when an electron is captured by the atom (or a molecule), forming an anion with a 1− charge. This is not necessarily directly related to the "willingness" for the element to ... WebJan 30, 2024 · The first electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous -1 ions.
