Question

. Explain the observations and conclusions drawn by Rutherford from alpha scattering experiment.

Answer 1

Observation And Conclusion Of Rutherford's Scattering Experiment. Most of the fast moving α-particles passed straight through the gold foil. Most of the space inside the atom is empty. Some of the α-particles were deflected by the foil by small angles.

Answer 2

Answer:

Rutherford Atomic Model – The plum pudding model is given by J. J. Thomson failed to explain certain experimental results associated with the atomic structure of elements. Ernest Rutherford, a British scientist conducted an experiment and based on the observations of this experiment, he proposed the atomic structure of elements and gave Rutherford Atomic Model.

Explanation:

experiment-

Rutherford’s conducted an experiment by bombarding a thin sheet of gold with α-particles and then studied the trajectory of these particles after their interaction with the gold foil.

Rutherford Atomic Model

Rutherford, in his experiment, directed high energy streams of α-particles from a radioactive source at a thin sheet (100 nm thickness) of gold. In order to study the deflection caused to the α-particles, he placed a fluorescent zinc sulphide screen around the thin gold foil. Rutherford made certain observations that contradicted Thomson’s atomic model.
