In a fashion similar to how the periodic table is used to characterize elements, a set of variables can be used to characterize chemical compounds and determine their quantum mechanical properties. For each element in the periodic table, all possible stoichiometries are displayed that can be obtained by repartitioning onto multiple atomic sites with variable atomic numbers, nuclear charges, and the Np protons that make up the atomic number. As presented by O. Anatole von Lilienfeld on page 1676, the cover image exemplifies the case of Np = 10 protons. Here, NI, ZI, and i are number of atoms in a given compound, nuclear charge of atom I, and stoichiometry index (sorted by increasing NI), respectively. Thus, each column corresponds to a different stoichiometry, various familiar compositions are pointed out, and in the limit of NI [RIGHTWARDS ARROW]1 the stoichiometry corresponds to Ne, while H10 is recovered for NI [RIGHTWARDS ARROW] Np
