Which physicist was famous for the gold foil experiment?

Correct option is D

The correct answer is: (d) Ernest Rutherford
Explanation:
· The Gold Foil Experiment was conducted by Ernest Rutherford in 1909 with the help of Hans Geiger and Ernest Marsden.
· It led to the discovery of the nucleus and proposed the Rutherford atomic model, where electrons orbit a dense, positively charged nucleus.
Information Booster:
· The experiment used alpha particles and a thin gold foil.
· Most alpha particles passed through, some deflected → indicating a dense nucleus.
· Replaced JJ Thomson’s plum pudding model.
· This was the foundation for modern atomic models.
· Rutherford is known as the Father of Nuclear Physics.
· Later discoveries led to Bohr’s model, improving upon Rutherford’s.
Additional Information:
· John Dalton – Proposed the Atomic Theory (1803).
· Niels Bohr – Developed the Bohr Model with electron orbits.
· JJ Thomson – Discovered the electron, proposed plum pudding model.
