The aim of  the present  research is calculation  the values  of total Stot stopping  power  which consisted from two parts :radiative SRad , collisional SColl of electrons  by employing Bethe-Bloch  relativistic formula. All the  related equations programmed via MathCad2012 by using the mean  ionization potential I value for Beryllium  in the energy range of (0.1-10)MeV, the results showing a that the collisional stopping power  is the dominate along the energy interval of incident electrons  than the radiative  stopping power  and the by comparing the  Stot values of Estar code with present results shows a in excellent agreement in especially in the  energies (0.1-3)MeV ,after  that,  the  Bethe-Bloch  relativistic formula show some discrepancies, which   requires  addition another corrections factors  to keeps the errors in results small.  



Keywords: Bethe-Bloch, stopping power, radiative, collision, Beryllium ,mean excitation  energy.
