"Electron Configuration" refers to the arrangement of the electrons in an atom into orbitals. We demonstrate how to follow the Aufbau Principle, filling in electrons into the orbitals of the Aufbau Diagram while obeying Hund's Rule and the Pauli Exclusion Principle. This video has 6 examples worked out in full: Hydrogen, Helium, Lithium, Beryllium, Boron, and Carbon. We also cover two exceptions to the Aufbau Principle: Chromium and Copper.
Stay tuned! Bonus features for this video are under development...
Our Chemistry Lessons playlist gives you practical help for the topics that chemistry students often struggle with. Each video has multiple example problems worked out in full. Topics covered include: Balancing Chemical Equations, the MOLE, Gas Laws, Molar Mass, and more.
