The episode starts with a recap of atomic structure (1:13) before it focuses on electrons. Using Heisenberg’s Uncertainty Principle as a background (2:10) it recaps electron configurations by comparing it to a small town set-up (3:05). We also discuss the Aufbau Principle (5:30) and connect the electron configurations to the periodic table (5:45). Hund’s Rule and Pauli Exclusion Principle are briefly described (7:05). An experimental approach to determine the electron configuration, the photoelectron spectroscopy (7:42), is introduced.
Question: What is the German term used for the rule that requires to start the electron configuration at the 1s level? (9:23)
