With new experimental information on nuclei far from stability being available, a systematic investigation of excitation energies and electromagnetic properties along the \(N=10, 11, 12\) isotones and \(Z=10, 11, 12\) isotopes is presented. The experimental data are discussed in the context of the appearance and disappearance of shell closures at \(N=Z=8,14,16,20\), and compared to an effective-interaction approach applied to neutrons and protons in \(d_{5/2}^{2,3,4}\) configurations. In spite of its simplicity the model is able to explain the observed properties.
