General Chemistry: Atoms, Molecules, and Energy

This lecture introduces the fundamental concepts of general chemistry, covering topics such as the structure of matter, chemical reactions, stoichiometry, acids and bases, chemical kinetics, and chemical equilibrium. It explores the atomistic nature of matter, the role of energy in chemical reactions, and the behavior of atoms and molecules. The lecture delves into the history of atomic theory, the current model of the atom, and the wave-particle duality of electrons. It also discusses energy quantization in atoms, the Bohr model, and the atomic hydrogen spectrum. Emphasis is placed on understanding the relationship between energy levels, electron configurations, and the stability of atoms.
