In this video, we dive into the world of electron configurations and explore why the old 2-8-8 method doesn’t apply to all elements. You’ll learn the reasons behind the Senior High School version of electron configuration, which offers a clearer and more accurate way of understanding how electrons fill atomic shells. By comparing the traditional 2-8-8 approach with the more complex 2n² method, we’ll help you grasp why this new method is better for explaining the behavior of elements beyond the first few. Perfect for students looking to deepen their understanding of chemistry and atomic structure!
