WebWe define the first electron affinity as the energy released when 1 mole of gaseous electrons are added to 1 mole of the element to form 1 mole of gaseous negative ions. First electron affinities are typically negative values. This is because when an electron is added to a neutral atom, energy is released in an exothermic process. http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch7/lattice.html
