Question

The electron affinity is defined as the amount of energy released when an electron is added to a neutral atom to form an anion. It measures the attraction between the incoming electron and the nucleus. The electron affinity of an isolated silicon atom is 1.39 eV while that of a neutral crystal is 4.02 eV. Explain why the electron affinity is larger for the silicon crystal.
