Preface
This text was written at the suggestion of the publishers from the notes of lectures
which I had given to advanced students for several years. It presupposes fundamental
knowledge of general inorganic chemistry and attempts to present the chemical
behavior of the nonmetallic elements in condensed form. The primary focus is on
simpl'e, easily-visualized compounds and reactions. Molecular structure is discussed
on the basis of current models of the chemical bond.
The important theoretical ideas of atomic structure and chemical bonding are treat-
ed in the first part of the book. Toward the end of this part empirical properties of
chemical bonds are introduced which lead on to the second, topically-oriented part.
Here the indispensable information about compounds and reactions becomes the
main theme, and theoretical concepts are enlarged and illustrated by numerous
examples which are interspersed in the representation of the factual material. The
simple theory of chemical bonding based on numerous approximations is shown to
be quite adequate for the interpretation of molecular structure, however, of little
help so far in the explanation of chemical reactions. Hence, a balanced presentation
of theory and factual material is required.

Translators' Preface
The marvelous variety and infinite subtlety of the non-metallic elements, their
compounds, structures and reactions, is not sufficiently acknowledged in the current
teaching of chemistry. It was our desire to bring to the English-speaking student the
new information available on this important class of elements, by preparing an
English translation of Professor Ralf Steudel's very successful text. The work opens
with a brief exposition of modern ideas of chemical bonding followed by a discussion
of hydrogen and the 22 elements which occupy the upper-right quadrant of the long
form of the periodic table. These elements, found above the zig-zag line convention-
ally drawn between aluminium, germanium, antimony and polonium and their
higher congeners, are outnumbered 4:1 by the metals, but form many more com-
pounds. The elements germanium and polonium are included among the non-
metals. The emphasis throughout is on structure and bonding, rather than the
compilation of an encyclopaedic listing of reactions.
In commending the book to its readers, the translators wish to acknowledge the
collaboration of the author Professor Ralf Steudel, and Dr. Rudolf Weber of
Walter de Gruyter in Berlin.
