The velocity dependency of the stopping cross sections was reported earlier by Firsov {\em et al} [6] and Lindhard {\em et al} \cite{Lindhard_1961}\cite{Sugiyama_1981} [7]. They have shown that there is a linear dependency of the electronic stopping power with the projectile velocity. In the low energy region, electron capture remains the most dominating process for the energy loss. But for metal the energy loss is due to the excitation of a small portion of electrons near the Fermi level to empty states in the conducting band. The energy loss in this case is primarily due to excitations of the targets. But at higher energies, there is a minimum momentum transfer of the projectile due to its short duration near the target. In this region the electronic curve has a maximum due to the limited response time of target bound electrons to the projectile ions.   In recent times, the development of time-dependent methods have enhanced the diverse study of  many body problems involving the slowing down of charged particles either in matters or gases[ref.] The time dependent density functional theory (TDDFT) on the other hand has enjoyed much consideration owing to its electron dynamics both self-consistency and non-perturbative way. [put more paper references here]. This paper involves an application of the TDDFT that embodies a plane-wave basis set for representing the electron dynamics(put prl, 39,40) accurately for proton impact collisions on a copper surface. We have tested the strength of this method to evaluate the electronic stopping $\mathrm(S_e)$. Our findings are compared with those due to stopping and range of ions in matter (SRIM) as well as available experimental values.
