Valency Clasical And Modern
The important point of difference is that the rare-earth metals show a nearly
constant tervalency, and bear such close Fig. 39. Genesis of the long periods in
the periodic system (after Herzberg). chemical likeness to each other that the
history of ...

Experimental Inorganic Chemistry
Hence the electronic 'promotion' from s*p to sp» must inevitably take place within
these atoms during chemical action, and tervalency be attained in their general
chemical behaviour. It is in line with this reasoning that the change in atomic ...

2 in the (tetragonal) crystals of the mercurous halides.f GROUP III (A) Boron (a)
The only non-metallic member of this group exhibits tervalency unambiguously in
the volatile halides BF3 (b.p. -101°), and BCl3 (b.p. 18-2°). BF3 resembles SiF4 ...

Linus Pauling: Selected Scientific Papers
It is seen from this example that the bivalency and tervalency shown by the
transition elements is not the result of the ease of removal of two or three
electrons from the atoms, but is rather a consequence of the electronegativity of
these ...

G. Wyrouboff further emphasized the possible tervalency of beryllium from the
analogies between the beryllium silico-tungstates and the corresponding
aluminium salt ; J. Blake also argued in the same direction from the likeness in
the ...

Aluminium and its congeners: including the rare earth metals
fourteen elements, the atomic weights of which lie between those of barium and
tantalum, are available for filling the vacancies between the positions of those
two elements. On the assumption of the tervalency of the rare earth elements,
then, ...
The next row in Figure 3.7 shows the three bond networks by which a CH unit
with four skeletal neighbors can use its skeletal tervalency, as in 1,6- C2B4H6,
that is, using two 2c–2e C–B bonds and one 3c–2e C---B---B bond, one 2c–2e C
–B ...

The predominant valence of boron, aluminium, indium and gallium is tervalency;
account for this. 7. Define the following: (a) Borides (b) Electron-deficient
molecule (c) Variable valency 8. Arrange the following in the increasing order of

A History of the Concept of Valency to 1930
Kekulé's successors of the present generation have been much exercised, and
not unsuccessfully, to show that in the case of nitrogen its five oxides incorporate
different manifestations of a constant tervalency; but in 1864 this could have been
...

... of salts derived from monobasic acids. Thus Muthmann in 1898 confirmed the
tervalency of lanthanum from the differences between the equivalent
conductivities of solutions of the chloride and the nitrate at dilutions of 32 and
1024 litres.
