    "abstract": "Shannon information entropies in position and momentum spaces and their sum\nare calculated as functions of Z (Z=2-54) in atoms. Roothaan-Hartree-Fock\nelectron wave functions are used. The universal property S=a+b lnZ is verified.\nIn addition, we calculate the Kullback-Leibler relative entropy, the\nJensen-Shannon divergence, Onicescu\u0027s information energy and a complexity\nmeasure recently proposed. Shell effects at closed shells atoms are observed.\nThe complexity measure shows local minima at the closed shells atoms indicating\nthat for the above atoms complexity decreases with respect to neighboring\natoms. It is seen that complexity fluctuates around an average value,\nindicating that the atom cannot grow in complexity as Z increases. Onicescu\u0027s\ninformation energy is correlated with the ionization potential. Kullback\ndistance and Jensen-Shannon distance are employed to compare\nRoothaan-Hartree-Fock density distributions with other densities of previous\nworks.",
