The nonlinear properties of ion acoustic shock waves in a magnetized electronegative plasma with nonextensive electrons and stationary dust grains are studied. The reductive perturbation technique is applied to derive the Zakharov–Kuznetsov Burgers (ZKB) equation. The Tanh method is used to obtain the shock wave solution. The present model is applied to four different electronegative plasma media which are found in space plasma, e.g. (H+, H−) plasma and (H+, O2−) plasma, and laboratory experiments, e.g. (Xe+, SF6−) plasma and (Ar+, O2−) plasma. It is found that the concentration of negative ions and the electron nonextensive parameter have important effects on the features of the propagated ion acoustic shock waves.
