JEE Main 2024 — 29 January, Shift 2 — Question 48
Given below are two statements : one is labelled as Statement I and the other is labelled as Statement II:
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 correct answer from the options given below :
- Option A:
Both statement I and statement II are false
- Option B:
Statement I is false but statement II is true
- Option C:Correct
Statement I is true but statement II is false
- Option D:
Both statement I and statement II are true
Answer: C
Step-by-step solution
According to Rutherford atomic model, most of mass of atom and all its positive charge is concentrated in tiny nucleus &
electron revolve around it. According to Thomson atomic model, atom is spherical cloud of positive charge with electron
embedded in it. Hence, Statement I is true but statement II false.
