Understanding Scandium's Electron Configuration

This video tutorial explains how to write the atomic orbital diagram for scandium. It begins with determining the electron configuration by following the periodic table pattern to account for all 21 electrons of scandium. The tutorial then demonstrates how to construct the atomic orbital diagram, showing the arrangement of electrons around the nucleus. The video concludes with a summary of the process.
