Rules for Electron Placement in Orbitals

Activity Purpose

Learn to write electron configurations by applying the Aufbau principle, Hund's rule, and the Pauli exclusion principle.

Content and Process

Orbitals and energy levels are shown visually. Rules for electron placement are applied step by step.

Learning Outcomes

Explains the Aufbau principle, Hund's rule, and the Pauli exclusion principle. Writes electron configurations for elements. Draws orbital diagrams.

To reinforce quantum numbers, orbital types and electron configuration, also read the Modern Atomic Theory guide.

Examine the historical development of atomic models from Dalton to the present day.
