Outline and Purpose of the Course Students are taught the structure of atoms and molecules, and the chemical bonds and structures of inorganic solids, which are basics of inorganic chemistry needed in order to work as researchers and engineers in all fields related to chemistry.
Course Goals To understand atomic structure, ionic bonds, covalent bonds, electronegativity, molecular structure, and basic crystal structures, which together form the foundations of inorganic chemistry.
Schedule and Contents Atomic structure (Chapter 1), 4 sessions
After receiving an overview of the origin, abundance ratio, and classification of chemical elements, students are given a general outline on the quantum mechanical method of expression for the orbitals of electrons in an atom and atomic orbitals, and are taught the orbital approximation method and the building-up principle for dealing with many-electron atoms. Additionally, students are given an explanation on atomic parameters such as the atomic radius and ionic radius that characterize the properties of an atom, ionization energy, electron affinity, and electronegativity, and are taught how these atomic parameters are related to the periodicity of properties of chemical elements.

Molecular structure and bonding (Chapter 2), 5 sessions
Based on the idea of bonding electron pairs, students are taught about Lewis structures, formal charge, oxidation number, resonance, and the relationship between the molecular structure and the characteristics of a bond (length and strength of a bond). Following this, the valence bond theory is explained, then concepts in the molecular orbital theory such as the bonding mode, expression of bond order, resonance, orbital overlap, and hybrid orbitals are explained for diatomic molecules and polyatomic molecules.

The structures of simple solids (Chapter 3), 5 sessions
The structures of many inorganic crystals are well explained by models that atoms and ions are regarded as spheres and they are closely packed. Here, the concepts of the crystal lattice and the close-packed structure of spheres that are needed for describing the structure of a crystal are explained. Following this, students are given an explanation about the structures of metal elements and alloys, and are taught about the characteristic structure of ionic solids, the effect of the cation to anion size ratio on the crystal structure, the concept of lattice enthalpy and the method of calculation using ionic models and thermodynamic data, and the various results derived from lattice enthalpy, among other matters concerning ionic solids in particular. Furthermore, students are also taught about the relationship between the electronic structure and the electrical/electronic properties of solids.
