Homework#2 (Graded)

. The goal of this homework assignment is to give
you practice calculating and understanding *effective nuclear
charge*.

The *effective nuclear charge* was
defined in lecture and also in the text index). Estimate the
effective nuclear charge for a valence electron in oxygen using
the Bohr formula for a one-electron ionization , but in which the
positive charge, Z_{eff}, attracting that one electron
accommodates the screening effect of all the other electrons
about the nucleus. The ionization energy is 1314 kJ/mol.
