Question

Q.1You have learned about three different models of the atom: Dalton’s model, Thomson’s model, and Rutherford’s model. What if Dalton was correct? What would Rutherford have expected from his experiments with gold?

Short answer

Answer

Rutherford had never observed the positive particles when Thomson’s model was correct.

Step-by-step solution

Step-by-Step SolutionStep 1: Rutherford’s experiment and his observation

The positively charged alpha particles will project on thin metal foil. There is a deflection of many particles at large angles, which can be reflected. This leads to the nucleus detection at the center of the atom.

Dalton’s model

Atoms are the smallest tiny particles. They are indivisible. If Dalton’s model were correct, there would be no subatomic particles.

Thomson’s model

JJ Thomson postulated the plum pudding model, which denotes the consideration of all atoms that diffuse a cloud of positive charge with negative electrons. It can be embedded in random. If Thomson were correct, alpha particles would travel through the foil with the path’s minor deflections. Rutherford would not have observed positive particles, i.e., protons.

Conclusion

Rutherford had never observed the positive subatomic particles, protons when Thomson’s model was correct.
