The energy change associated with adding an electron to a specified gas-phase atom or molecule, with sign convention stated explicitly.
wp-chem-periodic-tableopenstax-chemistry-2eiupac-periodic-tableEach relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Electron affinities provide a periodic energetic descriptor, with shell structure, correlation, spin, molecular environment, and sign convention producing important exceptions.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-chem-periodic-tableopenstax-chemistry-2eiupac-periodic-tableEach relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Electron affinity contributes to isolated-species electron-addition energetics, while complete redox free energies also depend on ionization, bonding, solvation, entropy, concentration, and coupled reactions.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
