Electron affinity is related to the formation of negative ions. Electron affinity can be defined as "the change in energy of a neutral atom when an electron is added to the atom forming a negative ion" To be more specific, energy (in kJ/mol) with regards to atoms (in a gaseous state/phase) Thus, the correct representation for the electron affinity of Li is [Li (g) + e - → Li - (g) ]
