WebApr 8, 2024 · Trends of Electron Affinity in Periodic Table. Factors Affecting Electron Affinity. The nuclear charge: The more positively charged the nucleus is, the greater the attractive force between the nucleus and electrons. As a result, atoms with more positive nuclear charges tend to have higher electron affinities.
WebElectron Affinity Trends. Electron Affinity is the energy associated with the addition of an electon to a gaseous atom. Example: Cl(g) + e- → Cl-(g) E.A. = -349 kJ/mol. Notice the sign on the energy is negative. This is because energy is usually released in this process, as opposed to ionization energy, which requires energy. north little rock 911WebA large amount of energy is released when the atom transforms into an ion. Hence, the electron affinity values are higher. Therefore, the electron affinity increases from left to right across a period, as shown in the image above. 2.
