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.
