The atomic propensity rules are investigated in weakly coupled degenerate quantum plasmas including the electron-exchange effect. The excitation probabilities, excitation cross sections, and orientation parameter are obtained as functions of the impact parameter, collision energy, electron-exchange parameter, Fermi energy, and plasmon energy. The results show that the electron-exchange effect enhances the excitation probabilities as well as the excitation cross sections. It is also found that the influence of the electron-exchange enhances the propensity of the 
excitation channel in weakly coupled degenerate quantum plasmas. It is also shown that the influence of the Fermi energy enhances the propensity of the excitation channel. However, it is found that the influence of the plasmon energy suppresses the propensity of the excitation channel in weakly coupled degenerate quantum plasmas. The detailed investigation on the variation of excitation preference is also given.
