We present results for the outer-shell electron-impact excitation of all Na-like ions from Mg+ to Kr25+ obtained using the intermediate-coupling frame transformation R-matrix approach. For each ion's calculation, the target and close-coupling expansions are both taken to be the 18 LS terms (32 levels) belonging to configurations [ 1s^22s^22p^6] 3l, 4l, 5l and 6l (l = 0-5). Effective collision strengths (Upsilons;) are presented at temperatures ranging from 2×10^2(q+1)2 K to 2×10^6(q+1)2 K (where q is the residual charge of ions, i.e. Z-11). Detailed comparisons for the Upsilons; are made with the results of previous calculations for several ions, which span the sequence. Furthermore, we examine the iso-electronic trends of both low- and high-temperature effective collision strengths
