Orbital Filling and Principles00:03:09

Explanation of the Pauli exclusion principle, the Aufbau principle for filling orbitals by energy levels, and Hund's rule for filling orbitals of the same energy.

Determining Electron Configuration00:04:38

A step-by-step guide to writing electron configurations for elements like chlorine, utilizing periodic table blocks and noble gas shorthand.

Magnetic Properties and Conclusion00:06:47

Overview of orbital diagrams, the difference between paramagnetic and diamagnetic atoms, and a final summary of how quantum numbers dictate atomic structure.
