a) Describe the differences between ionization energy, work
function and electron affinity.
b) Show their location with respect to Evac on a band
diagram.
Which of the following statements is false?
Electron affinity is a measure of the energy evolved when a
gaseous atom gains an electron
Anions are smaller than the parent atoms from which they are
derived
Ionization energies decrease as the atomic radius
increases
For isoelectronic cations, the higher the charge, the smaller
the ion
Cations are smaller than the parent atoms from which they are
derived
1. Define and predict trends in atomic
radii, ionic radii, ionization energy and electron affinity by
using the periodic table.
2. Differentiate between ionization
energy and electron affinity
3. Place the following atoms in order
of increasing atomic radius: N, O, P, Ge
