Krypton Electron Configuration Concepts

The video tutorial explains how to write the atomic orbital diagram for krypton by first determining its electron configuration. Krypton, with an atomic number of 36, has 36 electrons. The tutorial guides through filling the energy levels: 1s, 2s, 2p, 3s, 3p, 4s, 3d, and 4p, to complete the electron configuration. It then illustrates how to represent this configuration in an atomic orbital diagram, showing the distribution of electrons around the nucleus.
