Exercise
Form 3: Electrons and Electron Shells
In this exercise, students will dive into the fascinating world of electrons and their behavior within electron shells, exploring the relationship between atomic structure and chemical properties through interactive simulations and hands-on activities. By visualizing how electrons are arranged, students will gain a deeper understanding of concepts such as energy levels, bonding, and the periodic table.
