The cover illustrates how atomic basins allow splitting of the bond electronic distribution (BED) between attached atoms. On page 978 (DOI: 10.1002/jcc.23574), David Ferro-Costas, Ignacio Pérez-Juste, and Ricardo A. Mosquera introduce a novel electronegativity estimator, the gAH index, based on dividing (by means of quantum theory of atoms in molecules [QTAIM] basins) the BED of hydrogen-containing compounds described by natural localized molecular orbitals or electron localization function disynaptic basins. The periodic trends exhibited by this new estimator are shown for second and third periods. Its values are compared with the most popular electronegativity scales.
