In the following paper the element groups of the Halogens, of 
the Oxygen and Nitrogen group, and also those of the Carbon 
group will be treated. For the Hydrogen-Helium group considered 
here we have not found anything special — for the following 
groups, however, we shall find the remarkable fact that everywhere 
where (specially, for metals) the molecules of the elements consist 
only of one atom at 7, the value of Wa, becomes much greater 
than the normal one, calculated by us in I. These are only valid 
when two or more atoms are bound to each other in the molecule, 
so that the attraction cannot make itself fully felt in consequence 
of the mutually shadowing action. What we have found there 
Ge = resp dS, oy, de BE TED) mst VDE considered as a 
kind of rest attraction. If, namely, N, were entirely dissociated to 
N,, the attraction found by us for N,, viz. Yaz = 2,9 .10-°, would at 
once rise to about 80 (>< 10-2), hence to the tenfold value. 
We shall even have an opportunity to ascertain, that where in 
compounds as TeCl, and TeCl, the shadowing action gradually 
decreases, the value of War will already increase. Thus a, for 
TeCl, has the normal rest value 9. But for TeCl, Ya, will already 
have risen to the value 13. The non-saturate valencies, therefore, 
already make their influence felt. If, however, also the last chlorine 
atoms have been removed, the attraction of the Tellurium rises still 
more, and reaches the value 26. 
We shall find back this remarkable phenomenon for all metals; 
the exceedingly high values of melting point, boiling point, and 
critical temperature for many metals are owing to the high values 
of Va, in consequence of the monatomic state, from which ensues 
that the valence-attraction can make itself felt freely towards the outside.
