Repulsive electrostatic forces. Strong nuclear forces. Charged subatomic particles interacting with neutral subatomic particles. Stable nuclei contain a “magic” number of neutrons and protons, otherwise the nucleus will decay.
Students will act like they understand these terms by attempting to memorize the definitions, and all the explanations written down in class. And that’s the problem…students memorizing information and not actually learning the concepts. Subatomic particle interactions has always been a complicated concept for my students. I’ve done graphing, picture visuals, number analyzing, lots of stuff that is supposed to work. Yet it’s always a lower scoring portion on quizzes and tests.
