Electron Configuration and the Aufbau, Hund's, and Pauli Principles
A reading passage and summary packet that explains how electrons fill atomic orbitals using the Aufbau principle, Hund's rule, and the Pauli exclusion principle. It suits high school chemistry students reading at an 11th-grade level, and it builds scientific reading comprehension and the ability to predict electron configurations for ground-state elements.
Teacher Guide & Tips
- Assign the passage as a pre-lab or pre-lecture reading, or as a 30-40 minute independent reading followed by a short summary writing task.
- Discussion question: Why does Hund's rule require electrons to occupy empty orbitals of the same subshell before pairing up, and how does this affect an element's magnetic properties?
- Scaffold for struggling readers: Before reading, pre-teach the terms orbital, subshell, and ground state, and have students sketch a simple energy-level diagram to refer back to while reading.
- Extension for advanced students: Ask them to write the configurations for a transition metal and an ion of it, then explain where the exceptions to the Aufbau order appear and why.
- Estimated time: about 40 minutes for reading and summary, plus 10 minutes for discussion.
