Atomic Structure and Electron Configuration

The video tutorial explains how to write the atomic orbital diagram for bromine by first determining its electron configuration. Bromine, with an atomic number of 35, has 35 electrons. The tutorial guides through filling the energy levels according to the periodic table, starting from 1s to 4p, ensuring the correct number of electrons are placed in each orbital. The video also illustrates how to represent these configurations in an atomic orbital diagram, showing the distribution of electrons around the nucleus. The tutorial concludes with a visual representation of the atomic orbital diagram for bromine.
