11.34 Ionization energy is the energy required to re-
move a ground state (n 1) electron from an atom. It
is usually expressed in units of kJ mol-1. (a) Calculate
the ionization energy for the hydrogen atom. (b) Repeat
the calculation, assuming in this case the electron is
removed from the n 2 state.
11.35 Plasma is a state of matter consisting of positive
gaseous ions and electrons. In the plasma state, a mer-
cury atom could be stripped of its 80 electrons and
therefore would exist as Hg80+, Calculate the energy
required for the last ionization step-that is,
80+ (+ e
11.36 A technique called photoelectron spectroscopy is
used to measure the ionization energy of atoms. A sam-
ple is irradiated with UV light, which causes electrons
to be ejected from the valence shell. The kinetic energies
of the ejected electrons are measured. Knowing the en-
ergy of the UV photon and the kinetic energy of the
ejected electron, we can write
