Valency, Classical and Modern, Second Edition

This second edition was first published in 1959. The first four chapters present a compact elementary account of classical and modern conceptions of valency, suitable for the more general reader and for students preparing for university examinations. The concluding chapters are more advanced: chapter five shows how the electronic theory is applied to the heavier elements and their principal compounds; and the last chapter is devoted to current developments, and theories still in their early stages.
