Understanding Atomic Orbital Diagrams

This video tutorial explains how to write the atomic orbital diagram for manganese (Mn). It begins with determining the electron configuration based on manganese's atomic number, which is 25. The tutorial guides viewers through the process of filling energy levels and sublevels, such as 1s, 2s, 2p, 3s, 3p, 4s, and 3d, to account for all 25 electrons. The video also demonstrates how to draw the atomic orbital diagram, showing the arrangement of electrons around the nucleus. Finally, it discusses alternative notations for representing the diagram.
