Results of calculations of the electronic stopping power and the energy loss straggling for low velocity H-, He-, Li- and Be-like projectiles in the degenerate electron gas are reported. The Hartree-Fock-Slater description of the projectile and the dielectric function method were used. The size parameter Z__{min} of the charge distributions calculated from a variational principle depends on the characteristics of the medium. The stopping and straggling effective charges Z_{ef} of a projectile were analysed. They were found to differ with each other and to depend on the one-electron radius r_{s}, on the projectile atomic number Z_{i} and on the number of electrons N_{i} carried by the projectile.
