Orbital Diagrams and Electron Configuration

The video tutorial explains how to create orbital filling diagrams using Hund's rules for the ground state of atoms. It covers the subshell filling order, the number of orbitals in each subshell, and demonstrates how to fill these orbitals with electrons for elements like nitrogen and iron. The tutorial emphasizes the importance of electron spin and the arrangement of electrons in degenerate orbitals to achieve the lowest energy state.
