Answer 2

Answer:

Explanation:

Concept:

• The radioactive material is maintained in a lead box to focus the alhpa particles on the gold foil.
• Due to the high density of lead, alpha particles cannot flow through it.
• If, however, a boundary of lead is positioned in front of the radioactive material with a thin slit, only those alpha particles that can pass through the gap in the lead box will then proceed to strike the gold foil.
• The gold foil test was the most well-known experiment conducted by Ernest Rutherford.
• The gold foil was being targeted by an alpha particle beam.
• The gold is  placed in lead Block in Rutherford's experiment.
