Question

which of these statements is supported by the results of thomsons experiment? check all of the boxes that apply. atoms are indivisible. cathode rays are made up of negatively charged particles. atoms contain negatively charged particles.

Explanation:

• Thomson's experiment showed that cathode rays are deflected by electric and magnetic fields. Since opposite charges attract, and the rays were deflected towards the positive plate, this indicates that cathode rays are made up of negatively - charged particles.
• Also, since these negatively - charged particles (electrons) are emitted from atoms (as cathode rays come from the cathode which is made of atoms), atoms contain negatively - charged particles.
• Thomson's discovery of electrons disproved the idea that atoms are indivisible.

Answer:

B. Cathode rays are made up of negatively charged particles; C. Atoms contain negatively charged particles.
