Question

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.

• A. Both statement I and statement II are false
• B. Statement I is false but statement II is true
• C. Statement I is true but statement II is false
• D. Both statement I and statement II are true

Answer 1

The Correct Option is C

• According to Rutherford’s atomic model, most of the mass of the atom and all its positive charge are concentrated in a tiny nucleus, and the electrons revolve around it.
• According to Thomson’s atomic model, the atom is a spherical cloud of positive charge with electrons embedded in it.
• Hence: - Statement I is true as per Rutherford’s model. - Statement II is false because it is Thomson’s model, not Rutherford’s.

The Correct Answer is: Statement I is true but statement II is false
