This course is mainly for undergraduates in materials science and engineering and other related majors, including polymer and chemistry. Most of these disciplines involve and require knowledge of the formation of materials, the relationship between structure and performance. The understanding of materials from the atomic and structural level is the basis to the design, development and utilization of different materials. Therefore, this course aims to provide students with general chemical concepts and theoretical knowledge related to the formation of atomic structure and molecular structure, and on this basis, to introduce the relationship between structure and performance.

      First, we will introduce the historical evolution of the emergence of quantum mechanics, including the era of old quantum theory and the era of quantum mechanics. Subsequent course content contains the historical development of atomic structure, including Thomson model, Rutherford model, Bohr hypothesis (including Bohr radius, Bohr energy etc.). Subsequently, the concept of quantum mechanics was introduced to explain the basic principles of atomic structure, including the basic concepts and development history of quantum mechanics, shells, subshells, orbital energy levels, quantum numbers, hydrogen-like atoms, and the orbital shapes of electrons in atoms. On the basis of studying electronic behavior in atoms, we also discussed molecular structure and related theories, including valence electrons, ionization energy, affinity, electronegativity, and the formation mechanism of various chemical bonds. On the basis of these basic theories, a preliminary discussion of the relationship between molecular structure and shape and performance is discussed. 

     It is hoped that through the study of this course, students will understand and master the relevant basic concepts and basic theoretical issues of material structural chemistry, so that students will have a deep and clear understanding of the basic relationship between material formation and atomic structure, molecular formation and structure, and bond formation. In order to achieve the purpose of enabling students to have a clear physical concept of the nature of material formation. Students are expected to have a detailed understanding of atoms, electrons, orbitals and their basic theories related to the formation of materials, grasp basic concepts such as molecular formation, bonding, molecular orbital theory and bonding radius, and understand the energy levels and electronic structures of different materials that involve electricity and how to design new materials. 

Students are required to understand and master the relevant basic concepts and basic theoretical issues of material structral chemistry through the study of this course. It enables students to have a deep and clear understanding of the basic relationship between molecular formation and structure as well as bond formation and electronic structure. To help students build clear physics concept and learn fundamentals of material formationnature. Students should have a detailed understanding of atoms, electrons, orbitals and their basic theories related to materials formation, including valence bond theory and molecular bond theory as well as applications, like formation of engery band.
