• Excerpt from An Inorganic ChemistryThe majority of teachers will agree with the Author that Inorganic Chemistry presents a real difficulty to many of those beginning the study of this subject. In many cases this arises from the inability of the student to correlate and classify his observations. Hence the author has endeavoured to systematise the subject by giving a more than usual prominence to the Periodic System. Immediately after considering the reactions of the halogen and oxygen families of elements, this great generalisation has been developed, and in studying the remaining elements frequent recourse has been made to it. To aid the student still further in correlating and classifying chemical reactions and principles, the basic, amphoteric or acidic properties of the oxides have been emphasised, since the probable behaviour of compounds derived from the oxides can thus be predicted.This method of development has necessarily resulted in deferring the study of the Ionic Theory until the student has mastered the fundamental laws of the science. In itself this is no disadvantage because the student passes straight from the study of the ionic theory to the chemistry of the metals, where the theory may be most usefully applied.For the ideas concerning oxidation which have been developed in Chapter XI, the author is indebted to Professor B. D. Steele, D.Sc, F.R.S., who has found this method of dealing with the subject of great help to the student when considering the reactions and properties of the halogens.The author has endeavoured to avoid the introduction of a new law or generalisation until it has been found necessary for the interpretation of facts already described, and when the development of the subject requires a more exhaustive treatment, a separate chapter or section has been devoted to it.
