Atomic Structure and Isotopes

The video tutorial provides an overview of a lab activity using the element builder in PowerSchool. It explains how to use PDFs and Google Docs for the activity, discusses basic concepts of elements and atoms, and guides students through creating elements by adding protons, neutrons, and electrons. The tutorial covers mass number, atomic number, isotopes, and stability, and explains energy levels and electron configuration. It concludes with a brief overview of the periodic table and encourages students to complete the lab sheet and ask questions if needed.
