Abstract It is possible to compute the Debye characteristic tem-
perature QD from the heat c4pacity measured experimentall-
ly at a low temperature. q - A proportional to the
binding energy of the lattice of transition metals shows
a periciclicity of properties. The contraction changes
permit to interpret the changes of the binding force
within the group, various deviations from the linearity

Contid above the beaker in which the precipitation

duct the precipitation at 85'j. An important

The*degree of -polarity p of a compound as defined by Fajans could be
.-calculated only with the use of several experimentally stated vilues of P. The
concept of the "effective electric field intensity" F* = Z*-e/r of atoms and
-..ions .respectively was introduced ford4termining p quantitatively on the basis
of Fajanbl electrostatic approximati,om.("quantioule~theory") and from polari-
zation rules.. The effective nuclear, charge V wais calculated according to
Kohlrauseb. The radius is r a CLH(n*)?-/Z*. In equilibrium the
