This course explores the makeup of the physical world, from the properties and structures of matter to the laws explaining the activity of gases, as well as the chemical structures of elements, molecules, and compounds. Like other Chemistry courses, a rigorous course studies the periodic table of elements and the proper symbolic nomenclature of elements as well as the symbolic representation of chemical reactions in formulas and equations. Investigations into the microscopic world led to deeper understanding of the macroscopic world, from atomic structure and bonding to the properties of salts, acids, and bases
