Question

The particles which were deflected backward in Rutherford’s experiment were hit upon by

a) Nucleus

b) Empty space

c) Electrons

d) Protons​

Answer 1

Answer:

Both A and D are correct

Explanation:

This is because nucleus contains protons

Answer 2

Answer:

The particles deflected backwards in Rutherford's experiment were hit upon the Nucleus.

Explanation:

In the "Gold Foil Experiment '' by Hans Geiger, Ernest Marsden and Ernest Rutherford, Alpha particles were allowed to pass through a gold foil and observed its outcome through the other side with the help of a fluorescent screen. While some particles went straight through the foil some underwent serious deflection. This result made them realise the existence of the positive charge in an atom, protons,  concentrated in its Nucleus and the rest of the space is empty in an atom. This electric field in the nucleus caused the deflection of Alpha particles.

Till then the structure of an atom was considered as a sphere with a positive charge in which electrons scattered around, as proposed by J J Thomson. According to this model, the alpha particles going through a gold foil should not undergo any radical deflection. However, this was proved wrong with Rutherford's experience.
