using a cathode ray tube, thomson confirmed that\natoms must have an overall positive charge.\natoms include particles that have a negative charge.\nelectrons in atoms must have varying amounts of energy.\nelectrons are only found in the nucleus.
Answer
Brief Explanations:
Thomson's cathode - ray tube experiments led to the discovery of electrons. Electrons are negatively - charged particles.
- The first option is incorrect because atoms are neutral overall (protons + neutrons in nucleus and electrons outside).
- The third option about electrons having varying amounts of energy was not confirmed by Thomson's cathode - ray tube experiments (this is more related to later quantum - mechanical models).
- The fourth option is wrong as electrons are not in the nucleus (protons and neutrons are in the nucleus).
Answer:
atoms include particles that have a negative charge.
