Large-scale state-of-the-art shell model calculations with 2s1d and lower 2p1f shells are shown to present a unified description of N = 20 isotones with Z = 10–20, covering both stable and unstable nuclei. The calculations demonstrate that, although the N = 20 closed-shell structure remains for Z⩾14, the N = 20 shell gap vanishes naturally towards nuclei with Z⩾12, giving rise to various anomalous features including those in32Mg and31Na.
