Atomic Models & Alpha-Particle Scattering
Given below are two statements:
Statement I: Most of the mass of the atom and all its positive charge are concentrated in a tiny nucleus and the electrons revolve around it, is Rutherford's model.
Statement II: An atom is a spherical cloud of positive charges with electrons embedded in it, is a special case of Rutherford's model.
In the light of the above statements, choose the most appropriate from the options given below
Show answer and solution
Answer: (b)
- Statement I is exactly Rutherford's nuclear model: tiny massive positive nucleus with electrons revolving around it. True.
- Statement II describes Thomson's plum-pudding model, which is a different model, not a special case of Rutherford's. False.
- So the answer is (b).
