NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Thomson’s Model | (i) Positively charged nucleus |
| (b) Rutherford’s Model | (ii) Spherical cloud of positive charge |
| (c) Stability of Atoms | (iii) Accelerated electrons spiraling |
| (d) Energy Levels | (iv) Allowed energy states |
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-ii, b-iv, c-i, d-iii
D
a-iv, b-i, c-ii, d-iii
Correct Answer
Option A
Detailed Explanation
In Thomson’s model, an atom is described as a spherical cloud of positive charge with electrons embedded in it (a-ii), while Rutherford’s model concentrates the positive charge in a tiny nucleus (b-i). The stability of atoms is contradicted by the prediction of accelerated electrons spiraling into the nucleus (c-iii), and energy levels in an atom represent allowed energy states (d-iv).
