Atomic Orbitals and Electron Configuration

The video tutorial explains how to write the electron configuration and atomic orbital diagram for arsenic. It begins by identifying arsenic's atomic number and follows the process of filling electron orbitals according to energy levels. The tutorial then demonstrates how to represent this configuration in an atomic orbital diagram, showing the distribution of electrons around the nucleus. The video concludes by summarizing the key points of the electron configuration and orbital diagram for arsenic.
