Definition and characteristic

We infer from the results of our statistical analysis that the four scales of Table V are definitive and characteristic of the substituent interacting within a given pi framework. The pi interaction frameworks suggested are as follows... 

There are also certain other facts which appear to demand such a modification of Dalton s Atomic Theory as is found in the Electronic Theory. One of the characteristics of the chemical elements is that each one gives a spectium peculiar to itself The spectrum of an element must, therefore, be due to its atoms, which in some way are able, at a sufficiently high temperature, to act upon the ether so as to produce vibrations of definite and characteristic wave-length. Now, in many cases the number of lines of definite wavelength...

III. Apart from the external field used, every method for observing molecular symmetry has a definite and characteristic duration of observationy which we shall define as the average length of time for which a molecule can remain in an external field of the same direction. This length of time 0 may be limited (a) by the period of alternation of the external field, b) by the rotation of the molecules themselves.

Later advocates are Meldrum (see p. 737), Atkinson, and especially Soddy, whose intemperate statements were dealt with by the author. T. Dillon says To me, however, it seems that he failed to go as far as Dalton, whose real achievement was to attribute a definite and characteristic weight to the atom of each element but Dillon thought Dalton had read the Comparative Vietc, whilst Wheeler thought he had not. 

It is, however, to Hahy (1743— 1822) that we are indebted for the foundatioDB of the science of oiystallography. Hatty was the ttrst to point ont the fact that every crysttJline substance possesses certain definite and characteristic forms in which it ciystallizes, and that all these different forms can be derived from one fundamental form whiehcan be ascertained by measurement of the angles of the crystal Upon this principle he founded in 1801 his celebrated aystem of the classification of minerals.

One of the key factors in any corrosion situation is the environment. The definition and characteristics of this variable can be quite complex. One can use thermodynamics, e.g., Pourbaix or -pH diagrams, to evaluate the theoretical activity of a given metal or alloy provided the chemical makeup of the environment is known. But for practical situations, it is important to realize that the environment is a variable that can change with time and conditions. It is also important to realize that the environment that actually affects a metal corresponds to the microenvironmental conditions that this metal really sees, i.e., the local environment at the surface of the metal. It is indeed the reactivity of this local environment that will determine the real corrosion damage. Thus, an experiment that investigates only the nominal environmental condition without consideration of local effects such as flow, pH cells, deposits, and galvanic effects is useless for lifetime prediction.
