Atomic Orbitals and Electron Configuration

The video tutorial explains how to write the electron configuration and atomic orbital diagram for titanium. It begins by identifying titanium's position on the periodic table and its atomic number, which is 22. The tutorial then guides viewers through the process of writing the electron configuration by following the periodic table's pattern, filling each energy level sequentially. Finally, it demonstrates how to construct the atomic orbital diagram, illustrating the arrangement of electrons around the nucleus in various energy levels and orbitals.
