Electron Affinity Trend Science Trends

WebElectrons are attracted to the positively charged nucleus; therefore removing an electron requires energy. The process is endothermic, and so ionization energies have a positive value. The first ionization energy (Ei1) is the energy associated with the removal of an electron from the neutral gaseous atom. WebMar 2, 2024 · Electron affinity is most often reported in units of kilojoule per mole (kJ/mol). Sometimes the values are given in terms of magnitudes relative to each other. If the value of electron affinity or Eea is negative, it means energy is required to attach an electron. oakenclough children\\u0027s centre wilmslowWebElectron Affinity Chart.
