- In this study a comprehensive calculations of energies, hyperfine structure constants, Landé g$_J$ factors and isotope shifts have been performed for the lowest 71 states of Na-like Ar$^{7+}$, Kr$^{25+}$ and Xe$^{43+}$ ions. Radiative parameters viz., transition rates, wavelengths, oscillator strengths and lifetimes are also estimated for the electric and magnetic dipole and quadrupole transitions among these levels. The states under consideration includes $1s^2s^22p^6nl$ where n = 3 to 9 and l = s to i and fully relativistic multiconfiguration Dirac Fock method integrated in the latest version of general purpose relativistic atomic structure package is used. The relativistic calculation viz., Briet interactions and quantum electrodynamics effects are also included and their effects on energies are analysed. To inspect the reliability of MCDF results, we carried out another calculations using many body perturbation theory method integrated in Flexi Atomic code. A thorough comparison between the two obtained calculations and with the previous theoretical and experimental results, wherever available, is carried out and a good agreement is observed. The present calculations will considerably extend the already existing results for these Na-like ions as most of the results are reported for the first time Further, we believe that our results are of high accuracy and will be beneficial for spectral analysis and diagnosis in plasma and astrophysics.
