Welcome to Atomic Aura ⚛️

In this video, we review Question 2 from the 2024 A/L Chemistry Paper and understand the concepts behind electron configuration and orbital filling rules.

Before solving the question, we clearly explain:

• Aufbau Principle – how electrons fill orbitals according to increasing energy levels
• Hund’s Rule – electrons occupy degenerate orbitals singly before pairing
• How to identify violations of Aufbau Principle and Hund’s Rule in orbital diagrams

Then we analyze the 2024 A/L MCQ step by step and find the correct answer using these principles.

This explanation will help you quickly solve similar A/L chemistry MCQs in exams.
