摘要: The trend of various atomic properties (e.g., electron potentials, binding energies, scattering phase shifts) along the periodic system is examined utilizing available evidence from experiments and computations. Properties that depend primarily on different layers structure are seen to attain extreme values at columns table. From this plausible connection, one can see where how search for additional striking variations element next; e.g., elastic slow electrons thus indicated. analysis also contributes interpretation correlation properties.
