Electron Configuration Worksheet Answer Key Pdf - Each orbital diagram below violates one of the three rules of electron configuration. A number indicates the energy level (the number is called the principal quantum number.). For each diagram specify which rule (aufbau principle, hund's rule or pauli exclusion principle) is being violated, then explain the violation. Use the orbital filling diagrams to complete the table.
