Structure of the Atoms

1. Who discovered the electron and by which experiment?

J.J. Thomson discovered the electron through cathode ray tube experiments. This proved atoms are divisible and contain smaller particles. A strong exam answer should also explain how this point connects with Atoms are made of subatomic particles: electrons, protons, and neutrons, include one supporting event from the chapter, and end with a clear sentence showing the lesson learned.

2. How can students understand Atoms are made of subatomic particles: electrons, protons, and neutrons easily?

Students can first listen to the related audio explanation, then revise the key points and solve practice questions based on this topic. A strong exam answer should also explain how this point connects with Atoms are made of subatomic particles: electrons, protons, and neutrons, include one supporting event from the chapter, and end with a clear sentence showing the lesson learned.

3. How can Atoms are made of subatomic particles: electrons, protons, and neutrons be used in exams?

Students can mention the meaning, one example from the chapter, and one clear conclusion to write a complete answer.

Thomson proposed that the atom is a positively charged sphere with negatively charged electrons embedded like raisins in pudding. This model was later replaced but was an important step in atomic theory. A strong exam answer should also explain how this point connects with Protons were discovered through canal rays by E. Goldstein, include one supporting event from the chapter, and end with a clear sentence showing the lesson learned.
