Electron affinity, Eca, is the change in energy that occurs when an electron is added to a neutral isolated atom. This can be represented by the following equation: Part A X(g) +e-→X(g) Consider the following neutral electron configurations in which n has a constant value. Which configuration would belong to the element with the most negative electron affinity, Eca? Most electron affinity values are negative because energy is usually released when a neutral atom gains an electron. Eea values become more • View Available Hint(s) negative with increasing tendency of the atom to accept an electron and increasing stability of the resulting anion. Eea shows a periodic trend that is related to electron configuration. Elements with less than an octet and with high effective nuclear charge (Zeff) tend to have large negative Eea values. O 5s2 O 5s²5p? O 5s²5p³ Elements with filled valence shells or subshells and low Zeff tend to have Eea values near zero. O 5s25p®
