In a well-lit classroom, a male teacher wearing a lanyard gestures enthusiastically while explaining the electron-dot structure of ammonia (NH₃) on a chalkboard, labeled “Ammonia (anhydrous)” with 2e⁻ notation. Five diverse high school students sit at wooden desks, attentively taking notes, holding highlighters, and referencing open textbooks; a Flinn Scientific Periodic Table poster is visible on the wall. The scene captures active learning, collaboration, and foundational chemistry instruction.
