Lecture
This lecture covers the fundamental concepts of atomic structure, including the periodic table, atomic orbitals, and the organization of electrons in atoms. It delves into the Bohr model, quantum mechanics, wave functions, and the uncertainty principle. The instructor explains the quantum numbers (n, l, m, s) that define the state of an electron in an atom and the shapes of orbitals. Additionally, the lecture explores the quantum spin number and its role in defining electrons in orbitals.
