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.
