These worksheets test students’ knowledge of electron configuration and orbital diagrams. Students must have prior knowledge of Pauli Exclusion Principle, Aufbau Principle, and Hund’s Rule to understand how electrons fill up the various atomic orbitals. They should be capable of writing electron configurations and drawing orbital filling diagrams of the periodic table elements. Finally, they should be able to predict elements based on electron configuration and orbital filling diagrams.

Suitable for: Grade 8, Grade 9, Grade 10, Grade 11, Grade 12
