Question
Many classic experiments have given us indirect evidence of the nature of the atom. Which of the experiments listed below did not give the results described?
The Rutherford experiment proved the Thomson "plum-pudding" model of the atom to be essentially correct.
The Rutherford experiment was useful in determining the nuclear charge on the atom.
Millikan's oil-drop experiment showed that the charge on any particle was a simple multiple of the charge on the electron.
The electric discharge tube proved that electrons have a negative charge.
All of the above experiments gave the results described.
A.The Rutherford experiment proved the Thomson "plum-pudding" model of the atom to be essentially correct.

D.The electric discharge tube proved that electrons have a negative charge.
E.All of the above experiments gave the results described.
Explanation / Answer
Correct answer is A
Since Ernest Rutherford, a native of New Zealand, showed that the nucleus of an atom is very small and concentrated at the center of the atom, thus disproving the Thomson "plum pudding" model of the atom, I would say the first choice is incorrect.
