Polarizability (Part 1/2)

The video tutorial covers the concepts of polarizability and polarization using an atomic model. It explains the work-energy theorem and its relation to potential energy. The tutorial derives the electrostatic force and voltage, emphasizing the importance of these quantities in understanding atomic interactions. It also discusses potential energy in atoms, focusing on electron separation and its effects on energy levels. The video concludes with an analysis of how increasing atomic radius affects potential energy.
