MCQPhysics

NCERT · Class 12 · Physics · AtomsAccording to Thomson's atomic model, what is the distribution of positive charge and electrons in an atom?

Step-by-Step Solution

According to Thomson's atomic model (plum pudding model), the positive charge is uniformly distributed throughout the spherical volume of the atom, and the electrons are embedded inside it like plums in a pudding to maintain electrical neutrality.

Detailed Options Breakdown
Option : Positive charge is concentrated at the center and electrons revolve around it.

Incorrect choice. This distractor represents a common misunderstanding of the core principles of Atoms.

Option 1: Positive charge is distributed uniformly and electrons are embedded in it. (Correct Answer)

Correct choice. Refer to the step-by-step verified solution guidelines above for details.

Option 2: Electrons are concentrated at the center and positive charge surrounds them.

Incorrect choice. This distractor represents a common misunderstanding of the core principles of Atoms.

Option 3: Both positive charge and electrons are randomly scattered without any specific distribution.

Incorrect choice. This distractor represents a common misunderstanding of the core principles of Atoms.
