Answer

Brief Explanations:

Thomson's cathode ray tube experiment showed that cathode rays (electrons) are negatively charged particles within atoms. Let's analyze each option:

  • "atoms must have an overall positive charge": Thomson's model (plum - pudding) had positive charge as a "soup" with electrons, but the experiment didn't confirm overall positive charge of atoms.
  • "atoms include particles that have a negative charge": This is correct. The cathode ray tube experiment identified electrons (negatively charged particles) in atoms.
  • "electrons in atoms must have varying amounts of energy": This is related to later models (like Bohr's) about electron energy levels, not Thomson's experiment.
  • "electrons are only found in the nucleus": Electrons are outside the nucleus; protons and neutrons are in the nucleus. This is incorrect.

Answer:

B. atoms include particles that have a negative charge. (Here we assume the options are labeled as A, B, C, D with B being "atoms include particles that have a negative charge[SSE Completed, Client Connection Error][SSE Completed, Client Connection Error][LLM SSE On Failure]
