Molecular volumes and structural chemistry

A list of atomic parachors is given and with its aid, parachors and molecular volumes of all kinds of molecules may be estimated. It is suggested that the atomic volume of a given element depends upon its electronic state so that the study of molecular volumes can throw light upon structural problems in chemistry, and this is illustrated by a consideration of certain compounds of the transition elements. In addition, examples are given to show how parachor values are likely to prove helpful in the study of ions in aqueous solutions.
