| contents | We present relativistic many-body calculations of total electron binding energy of neutral atoms up to element $Z=120$. Binding energy for ions may be found by subtracting known ionization potentials. Accuracy of the results for $17<Z \le105$ significantly exceeds that in NIST tables (there are no data for $Z>105$ there). We fit numerical results for binding energies by analytical function of $Z$. We also calculate numerical values and determine dependence on $Z$ of the correlation corrections, Dirac and Breit relativistic corrections and quantum electrodynamics (QED) corrections. |
