Periodic Table and Stoichiometry

This lecture covers the periodic table, Aufbau principle, Mendeleev's classification, atomic properties, stoichiometry, isotopes, atomic and mass numbers, electron configuration, ionization energy, electronegativity, and chemical reactions. It explains the relationships between atomic properties and the periodic table, the concept of isotopes, and the calculation of atomic mass. The lecture also discusses the principles of chemical reactions, including balancing chemical equations and determining the limiting reactant and reaction yield.
