Determine the Hamiltonian for Multi-Electron Atoms #2 (Lithium)

The video tutorial explains the process of deriving the Hamiltonian for a lithium atom, a multielectron system. It covers the concepts of kinetic energy, potential energy, and the forces of attraction and repulsion between electrons and the nucleus. The tutorial emphasizes the importance of drawing free body diagrams to visualize these forces and systematically add up the energy terms to construct the Hamiltonian. The process is described as mechanical and repetitive, highlighting the challenges of solving larger systems analytically.
