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?

A. The Rutherford experiment proved the Thomson "plum-pudding" model of the atom to be essentially correct.

B. The Rutherford experiment was useful in determining the nuclear charge on the atom.

C. Millikan's oil-drop experiment showed that the charge on any particle was a simple multiple of the charge on the electron.

D. The electric discharge tube proved that electrons have a negative charge.

E. All of the above experiments gave the results described.

Option A, The Rutherford experiment proved the Thomson "plum-pudding" model of the atom to be essentially correct.

Explanation:

Thomson's plum pudding model:

Plum pudding model was proposed by J. J Thomson. In Thomson's model, atoms are proposed as sea of positively charge in which electrons are distributed through out.

Result of Rutherford experiment:

As per Rutherford's experiment:

Most of the space inside the atom is empty.

Positively charge of the atom are concentrated in the centre of the atom known as nucleus.

Electrons are present outside the nucleus and revolve around it.

As it is clear that, result of Rutherford experiment did not supported the Thomson model.
