Atomistic
Atomistics studies the structure and behavior of atoms, hence its importance in better understanding and assimilating chemistry and the structure of matter. It is mainly concerned with: - To the fundamental elements of matter: atoms made up of protons, neutrons and electrons. - To know how these subatomic particles interact with each other to form atoms, then molecules. Atomistics is a branch of chemistry devoted to the descriptive study of the internal structure of the atom, its properties and the energy exchanges within it. Historical atomic models, from Thomson to Bohr, have evolved to provide an increasingly accurate picture of atomic structure. Each model made important contributions while having its own limitations, paving the way for modern theories of quantum mechanics and the current understanding of atomic structure. These models demonstrate the evolution of our understanding of atoms, moving from a simplistic view to a complex, quantized description of electrons and nuclei. Chemistry is a vast science due to the breadth of its field of investigation: matter in all its forms. Nevertheless, a few generally simple concepts are sufficient to interpret and understand most of the phenomena that occur in the universe. - The first step is therefore to distinguish between the different fields of science: physics, biology, geology, chemistry, and medical sciences. We deliberately set aside mathematics, which is only a tool for shaping these different sciences and structuring them within a logical framework. - There are many ways to present chemistry logically. We choose to base ourselves on the fundamental concept of the atom. From this, other concepts such as the chemical element, then valence, chemical bond, and finally chemical reaction will be deduced. This latter term, which, in general, deals essentially with the structure of the atom and the nature of the chemical and physical bonds encountered in the various states of matter, hence the title of this work is called "Atomistics". Atomistics is the subject of four chapters in which are associated multiple choice questions and exercises that should allow the student to properly assimilate the course of atomistics provided in this book. The latter aims to bring together the essential concepts, fundamental notions and reasoning to be well mastered to approach the exercises of direct application of the proposed course. I hope to make this work a clear and pleasant working tool for students and teachers to consult. The Logic of Chemistry : A Story of Electrons.
