Atomic physics techniques like Penning trap mass spectrometry and laser spectroscopy have provided sensitive and high-precision tools for a detailed study of nuclear ground-state properties far from the valley of stability. Mass, moment and nuclear charge radii measurements in long isotopic and isotonic chains have allowed, e.g., to extract nuclear structure information such as shell and subshell closures, the onset of deformation, the coexistence of nuclear shapes at nearly degenerate energies, and so on. This contribution covers experimental techniques to study nuclear ground state properties and their applications for mainly nuclear structure studies but also in other fields as, e.g., nuclear astrophysics since to a large extent, the paths of element formation are determined by ground (and partly isomeric)-state properties of nuclei.
