Question

Which model of the atom was used as a result of JJ Thomson's cathode ray

experiments?
a. Plum pudding model
b. Nuclear model
C. Planetary model
d. Quantum mechanical model

Answer 1

a. Plum pudding model

Step-by-step explanation:

The plum pudding model of the atom was proposed by J.J. Thomson. It was the model he derived from his experiment on the gas discharge tube.

J.J Thomson was the first person to discover electrons which he called cathode rays because in the discharge tube, they emanate from the cathode.

• This led him to suggest the plum pudding model of the atom.
• The model reflects electrons being surrounded by a volume of negative charges.
