In Rutherford's experiment, a thin gold foil was bombarded by alpha particles. If Thomson's "Plum Pudding Model" of the atom were correct, what would have been the outcome of the experiment?

Consider the following statement:

(I) All isotopes of elements have the same number of neutrons.

(II) Only one isotope of an element can be stable and non-radioactive.

(III) All elements have isotopes.

(IV) All isotopes of Carbon can form chemical compounds with Oxygen$-16$.

The correct option regarding an isotope is:

In Thomson's experiment for the determination of $\left(\frac{\mathrm{e}}{\mathrm{m}}\right)$ of electron, electric field of intensity $\text{'}\mathrm{E}\text{'}$ only is applied. Now the deflection produced by the electron beam is directly proportional to:

A beam of fast moving alpha particles were directed towards a thin film of Gold. The parts $A^{\text{'}}, B^{\text{'}}$ and $C^{\text{'}}$ of the transmitted and reflected beams corresponding to the incident parts $A, B$ and $C$ of the beam are shown in the adjoing diagram. The number of alpha particles in
