Inorganic chemistry covers a wide variety of disciplines, dealing with all elements in the periodic table. The aim of this class is to understand properties of elements and their compounds (e.g., chemical bonds, physical property, and reactivity) by focusing on electronic structures of atoms and molecules. The lecture starts with behaviors of electrons in atoms, which determine properties of elements, then moving on atomic parameters, changeable periodically, such as ionization energy, electron affinity, and electronegativity. In the molecular bonding theory section, the instructor tells you how to describe covalent molecules based on valence bond theory and VSEPR rule. Besides the basics of molecular orbital theory is introduced as a means of describing covalent molecules by referencing a simple diatomic molecule. The inorganic solids’ section includes the structures of ionic solids and metals, band theory, and the related thermodynamics. In the section of acid and base, the lecture begins with the definition of acid and base, and deals with factors governing acid strength by focusing on electronic configuration and molecular orbitals.
This class requests you to acquire fundamental knowledge on inorganic chemistry, thereby establishing a strong backbone toward upcoming more advanced classes. By repeating to ask yourself “why it is so?” and “why something happens?” and striving to gain essence of inorganic chemistry, you will be able to have a strong general foundation that may help you to understand a wide range of chemistry.
At the end of this course, students will be able to:
(1) explain/understand properties of elements and ions, based on the periodic table of the elements.
(2) explain reactivity of chemical species and stability of compounds.
(3) explain chemical bonds that consist of various materials.
