Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1915 edition. Excerpt: ...only occurs when an atom, acting positively, has a valence less than its maximum; for negative valence is fixed--for example, an atom with six valence magnetons can part with any number up to six, but to make up a group of eight within itself it must take in exactly two. The formulse explain themselves. In most of such molecules the unsaturated atom has a pair of free magnetons, which is represented by the symbol AThis tendency of free magnetons to go in pairs is referred to again below. Now these free magnetons may be expected to produce two effects in the molecule. 0ne is obvious: it is a tendency to form the corresponding saturated molecule, C02, PCl5, S03, N20s, N204, and so lower the magnetic energy. But this must always raise the electric energy--e. g., in S02 the S atom has lost four magnetons, in S0s six--and that tends to oppose saturation. The point of equilibrium between these two tendencies, apart from metastable conditions ofthe molecule, will naturally be further and further from the point of saturation as we pass from group IV to group VIII of the Periodic Scheme: an inspection of the oxides in these groups shows that this prediction agrees with the facts. The other effect is due to their influence upon what linkages are already formed. We have seen ( 11) that free magnetons weaken neighboring groups of eight. This results in a tendency for unsaturated molecules to break down in such a way as to form molecules of other types that are more saturated, if that is possible. This may occasionally take place by the formation of the molecules of the elements, as in the reaction-2(-@(c)+(aa) A. but more often by a change of the following type: which combines the two effects of the free magnetons. Changes of type A do not.show more
