Understanding Rutherford's Atomic Model

What was the main idea behind J. J. Thomson's 'Plum Pudding' model?

• Electrons are embedded in a positively charged cloud.

• Electrons orbit the nucleus in fixed paths.

• Atoms consist of a central nucleus surrounded by electrons.

• Atoms are mostly empty space with a dense nucleus.

What unexpected result did Rutherford observe in his gold foil experiment?

• Some alpha particles were deflected at large angles.

• Alpha particles emitted light when hitting the foil.

• Alpha particles were absorbed by the gold foil.

• All alpha particles passed through the foil without deflection.

What did Rutherford conclude about the structure of the atom from his experiment?

• Atoms have no internal structure.

• Atoms are made entirely of electrons.

• Atoms have a dense, positively charged nucleus.

• Atoms are solid spheres.

What is a major limitation of Rutherford's Nuclear Model according to classical electrodynamics?

• It claims that protons and electrons are the same.

• It suggests that atoms are indivisible.

• It states that atoms cannot emit light.

• It predicts that electrons should spiral into the nucleus.

Despite its limitations, what was a significant contribution of Rutherford's model?

• It provided a fundamental understanding of atomic structure.

• It described the quantum nature of electrons.

• It introduced the concept of atomic isotopes.

• It explained the chemical behavior of elements.
