Electron affinity is rarely applied to second or third electron affinity levels because the elements are so unstable, and thus unable to survive long in nature. If they do exist the values for the electron affinities are all positive. Introduction: The periodic table is so named because similar patterns repeat, or appear periodically, throughout the table.

Text lists sorted by: Value | Atomic Number Click here to buy a book, photographic periodic table poster, card deck, or 3D Electron Affinity Patterns on the Periodic Table Electron affinity values are related to nuclear charge and shielding. Because the nucleus is positively charged and electrons are negatively charged, the greater the charge of the nucleus, and the lower the shielding by electron shells, the more likely an atom will be to add an electron, and the Thus, large electron affinity value indicates the tendency of forming stable negative ions and low electron affinity values indicate tendency to form positive ions. e.g.- Chlorine – 1s 2 2s 2 2p 6 3s 2 3p x 2 3p y 2 3p z 1 – just needs one electron to complete octet in the third shell(3s and 3p).It has two 3s +five 3p = 7 electrons in the Electron affinity increases upward across periods of a periodic table for the groups and from left to right, because the electrons added to the energy levels get closer to the nucleus, making the nucleus and its electrons more attractive.

As you move down a group, electron affinity decreases because the atom gets larger and the nucleus (with positive charges) is further away from the edge of the atom so it is harder to attract Electron Affinity: The following periodic table shows the known electron affinity data for the elements. The values are confined to the main group elements because the transition metals, lanthanides, and actinides, which comprise the bulk of the elements, form stable cations, not stable anions. Electron affinity is a measure of the energy released when an extra electron is added to an atom.
