Rutherford's Gold Foil - Part 1

What was the widely accepted model for the structure of an atom before Rutherford's experiment?

• Bohr Model

• Plum Pudding Model

• Quantum Mechanical Model

• Dalton's Atomic Theory

What was the primary goal of Ernest Rutherford's Gold Foil experiment?

• To discover new elements.

• To study the properties of light.

• To understand the structure of an atom.

• To measure the speed of alpha particles.

Why did Rutherford choose alpha particles for his experiment?

• They are negatively charged.

• They are very light and fast.

• They have high energy and are heavier than protons.

• They are easily produced in large quantities.

Which component was used in Rutherford's Gold Foil experiment to detect the alpha particles?

• Lead container

• Gold foil

• Fluorescent screen

• Source of alpha particles

What was an unexpected observation in Rutherford's Gold Foil experiment that contradicted the Plum Pudding Model?

• All alpha particles passed straight through the foil.

• Most alpha particles were absorbed by the foil.

• Some alpha particles were deflected by small angles, and a few rebounded.

• The gold foil melted due to the alpha particles.
