Question

what did Rutherford observe that surprised him?

A. most of the alpha particles shot at the gold foil bounced back.

B. most of the alpha particles shot at the gold foil went straight through the foil.

c. none of the alpha particles went through the gold foil.

D. all of the alpha particles went straight through the gold foil.

Answer 1

Answer:

Some of the Alpha particles shot at the gold foil bounced back.

Explanation:

Answer 2

Rutherford observed that most of the alpha particles shot at the gold foil went straight through the foil.

Why Rutherford was surprised?

The alpha-particle scattering experiment is an important experiment that led Rutherford to give an accurate description of the distribution of positive and negative charges within the atom. Alpha particle source is placed in the lead cavity. The alpha particles emitted by the source are collimated into a narrow beam with the help of lead and slit.

The observations of Rutherford’s Alpha Scattering Experiment are: First, he observe that most of the α-particles that are bombarded towards the gold sheet pass away the foil without any deflection, and hence it shows most of the space is empty.

The correct answer is option B.
