Assertion : Thomson’s atomic model is known as ‘raisin pudding’ model.
Reason : The atom is visualized as a pudding of positive charge with electrons (raisins) embedded in it.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

The correct Answer is:
**Solution:** 1. **Understanding the Assertion**: The assertion states that Thomson's atomic model is known as the 'raisin pudding' model. This is accurate because J.J. Thomson proposed this model to describe the structure of the atom. 2. **Understanding the Reason**: The reason provided explains why it is called the 'raisin pudding' model. In this model, the atom is visualized as a sphere of positive charge (the pudding) with negatively charged electrons (the raisins) embedded within it. This representation helps to explain the overall neutrality of the atom. 3. **Connecting Assertion and Reason**: Both the assertion and reason are true. The assertion correctly identifies the name of Thomson's model, and the reason accurately describes the visual representation of the model. Therefore, the reason serves as a correct explanation for the assertion. 4. **Conclusion**: Since both the assertion and the reason are true, and the reason correctly explains the assertion, we conclude that the statement is valid. **Final Answer**: Both the assertion and reason are true, and the reason correctly explains the assertion. ---

Why did Thomson atom model fail?

Which model of atom suggests that atom is a spherical cloud of positive charges with electrons embedded in it?

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.

De Broglie Wavelength | Thomson Atomic Model

Assertion (A ): Bohr model is not applicable for multi-electron model. Reason (R ): Bohr model cannot account for sublevel (s, p, d,f) orbitals and electron spin.
