Rutherford's Alpha Scattering Experiment

Q.

From the $\alpha$-particle scattering experiment, Rutherford concluded that

1. $\alpha$-particles can come within a distance of the of ${10}^{-15}m$ of the nucleus.

2. The radius of the nucleus is less that ${10}^{-15}m$.

3. The scattering follows Coulomb's law.

4. The positively charged parts of the atom move with extremely high velocities.

Q.

When alpha particles are sent through a thin metal foil, most of them go straight through the foil because :

1. alpha particles are much heavier than electrons

2. alpha particles are positively charged

3. most part of the atom is empty space

4. alpha particles move with high velocity

Q.

According to Rutherford's model, the positive charge is concentrated in a very small volume. (True/False)

1. True

2. False

Q.

Rutherford's experiment on scattering of $\alpha$-particles showed for the first time that the atom has

1. Protons

2. Nucleus

3. Neutrons

4. Electrons

Q.

In Rutherford's scattering experiment, which of the following does not happen?

1. Most of the α-rays pass through without deflection.

2. A few α-particles pass through the nucleus.

3. A few α-particles are deflected back.

4. α-Particles going near the nucleus are slightly deflected.

Q.

Rutherford's alpha particle scattering experiment eventually led to the conclusion that

1. Mass and energy are related

2. Electrons occupy space around the nucleus

3. Neutrons are buried deep in the nucleus

4. The point of impact with matter can be precisely determined
