Electron impact triple differential cross section (TDCS) results are reported for the single ionization of Be(2s), Be(1s), Be 2+ (1s) and Be + (2s) targets. The differential cross sections have been calculated in the modified distorted wave formalism under different kinematical conditions for the coplanar emission of electrons. Due to unavailability of experimental data, we have made a careful comparison of Be and it's ions TDCS with the trends of TDCS measured for He and Li targets, which have similar electronic configurations as Be +2 and Be + respectively. Similarity in the trends of TDCS are observed for He(1s); Be 2+ (1s) targets, Li(2s); Be + (2s) and Be(1s); Be 2+ (1s) targets. Effects of iso-electronic and iso-nuclear configurations on collision dynamics are observed in the trends of TDCS.
