Inorganic chemistry is the chemistry of all the periodic table elements and includes the synthesis of the largest volume chemicals on Earth, the key energy-generating reactions and catalysts needed for a green planet, and compounds exploited in modern electronic and photonic devices. This is the first part (followed by CHM237H1 and then CHM338H1) of a two-year sequence illustrating the rich variety of structures, physical properties, and reactions of compounds of the elements across and down the periodic table. It includes fundamentals of bonding, symmetry, and acid-base/ redox reactions of molecular compounds and transition metal complexes and applications of this chemistry in the world. CHM236H1 is recommended for students interested in broadly learning about chemistry across the periodic table.
