Question

We know that the Rutherford model of the atom is superior to the Thompson model because when alpha particles are scattered from atoms:

• A. the deflected angle is usually small
• B. some alpha particles are deflected to large angles
• C. they are usually observed with kinetic energy between 5 and 10 MeV
• D. the deflected angle is always large

Answer 1

The correct option is B

some alpha particles are deflected to large angles

We know that the Rutherford model of the atom is superior to the Thompson model because when alpha particles are scattered from atoms, some alpha particles are deflected to large angle. This led to the conclusion that the whole of positive charge and nearly entire mass of the atom were concentrated in a tiny central core named nucleus then.
