Which of the following observations indicates that atoms of all elements contain small, negatively charged particles? Alpha part

icles are repelled by cathode rays of elements. Cathode rays are deflected towards a positively charged rod. A particular frequency of light is produced by a gas in an excited state. Certain areas of the atom called orbitals contain all the charged particles.

Answer:

The correct option is;

Cathode rays are deflected towards a positively charged rod

Explanation:

Cathode rays are beam of electrons emitted from the cathode in a vacuum tube and moving towards the anode, due to the difference in the voltage between the electrodes

The discovery of the electrons was through the proof by Thomson that cathode rays were a negatively charged, previously unknown particle, which was to become known as the electron.
