      Explanation:
      • Electrons, protons and neutrons are Fundamental particles and Neutrino is known as subatomic particles
  2. Electron was discovered by:
    1. Rutherford
    2. Goldstein
    3. J.J Thomson
    4. Chadwick
      5. Show Answer
      Answer: C
      Explanation:
      • N/A
  3. Electron was discovered in the year;
    1. 1909
    2. 1896
    3. 1913
    4. 1886
      5. Show Answer
      Answer: B
      Explanation:
      • N/A
  4. Cathode rays are so called because these rays are;
    1. emitted from positive electrode
    2. emitted from negtive electrode
    3. produced by ionization of gas
    4. negativlely charged particles
      5. Show Answer
      Answer: B
      Explanation:
      • N/A
  5. Cathode rays are simply;
    1. electrons
    2. protons
    3. neutrons
    4. alpha particles
      5. Show Answer
      Answer: A
      Explanation:
      • Cathode rays consist of stream of electrons
  6. Cathode rays are produced at pressure;
    1. 760 torr
    2. 0.01 torr
    3. 350 torr
    4. 50 torr
      5. Show Answer
      Answer: B
      Explanation:
      • Residual gas in the discharge tube causes hinderance, so preesure is kept low
  7. Cathode rays can cast shadows of mettalic objects placed in their path. This shows that they;
