The following explains the rationale for the order in which the chapters are presented in this book
Chemistry is the study of the physical and chemical properties of the matter in the world around us.
In all cases this matter comprises simpler particles
The first section, fundamental knowledge, looks evidence for the particulate nature of matter, the kinetic theory.
The second section, atomic theory, investigates the very nature of the most fundamental particles, the atoms
The forces of nature must be used to aggregate the fundamental particles, i.e. to bond them together into larger particles and aggregations of matter. This then leads into the structure and bonding section.
Only once students appreciate the complexity of the particles involved can they start to discuss the quantitative nature of chemical and physical interactions in the stoichiometry section.
