A Comprehensive Treatise on Inorganic and Theoretical Chemistry
There is no objection to the assumed quadrivalency of oxygen. In fact, it is highly
probable that oxygen, like its companions — sulphur, selenium, and tellurium —
in the periodic system can be bi-, quadri-, or sexi-valent. 0. Wolkowicz ]5 ...

From Classical to Modern Chemistry: Some Historical Sketches
In 1858 an important paper which dealt with the quadrivalency of carbon and the
linking of carbon atoms was published by Couper. His approach to the subject
was on different lines from those adopted by Kekule, and he preceded him in ...

group, quadrivalency is maintained in all the more stable compounds of these
metals.

Cotton in India: a monograph
Brown and Menzel (1952a) compared the degree of bivalency shown by the
triploid hybrids, Hirsuta x a diploid species, with the degree of quadrivalency
shown by the derived hexaploids. Quadrivalency in the hexaploids was much
less than ...

The second formula is based on the assumption of the quadrivalency of oxygen.
This assumption, whilst it may explain the constitution of this hydrochloride, does
not satisfactorily explain the constitution of such compounds as 2(CH3)sPO ...

The quadrivalency of vanadium is so strong that some compounds of V,Os
spontaneously lose oxygen to form compounds containing V204. Niobium and
tantalum are usually regarded as typical quinquevalent elements, but they have
also a ...

... the relatively abundant thermodynamic data for thorium species are of value
because of the position of thorium as the first member of the actinide series to
show quadrivalency. The data for Th(IV) species are therefore of considerable
