Use Spartan or WebMO to calculate the electron affinity of atoms with atomic number 1~10, by using CCSD(T)、B3LYP and MP2 theories with d-aug-cc-pVTZ basis sets and add an S orbital and an P orbital diffuse functions to the 6-31++G(d,p) basis set, and do some simple statistical analysis. The unit of the electron affinity should be presented as kcal/mol .
