Question

what is the difference in atomic models of thomson and rutherford?

Answer 1

Thomson proposed the plum pudding model of the atom. The model was named after the consistency of plum pudding with raisins floating throughout. The pudding represented a positively charged filling in which negatively charged electron "raisins" floated. According to the model, the filling was roughly the same consistency everywhere in an atom.

Rutherford, proposed that the plum pudding model was incorrect, because each atom contained a central nucleus. To test his thesis, Rutherford shot alpha rays at a sheet of gold only 1/3000 inch thick. If Thomson's model were correct, every alpha ray would shoot through the sheet of metal because the ray would simply pass through the atom's "pudding." However, Rutherford noticed that some rays shot back. This implied that they bounced off something solid, which Rutherford thought was a central nucleus. He thus added this component to Thomson's model, which had no central nucleus.

Answer 2

Answer:

Explanation:Acceleration = (Final velocity - Initial velocity )/ Time

Acceleration = (0 - 50) /  5

Acceleration = -50 / 5

Acceleration = -10m/s^2
