Phosphorus Atomic Orbital Concepts

The video tutorial explains how to write the atomic orbital diagram for phosphorus. It begins by determining the electron configuration of phosphorus, which has 15 electrons. The tutorial follows the periodic table to fill the electron orbitals, starting from 1s to 3p. The video then demonstrates how to construct the orbital diagram using the electron configuration, explaining the arrangement of electrons around the nucleus. Finally, it provides a visual representation of the orbital diagram, showing the distribution of electrons in different energy levels.
