Amongst the following statements, which was not proposed by Rutherford’s scattering experiment?

Options

A. Most part of an atom is hollow
B. `alpha` particle, due to its high mass and charge suffers neglegible deflection by an electron
C. A very few -particles bounced back on their original path
D. Most of the -particles suffer significant deflections from their original path

Explanation

To determine which statement was not proposed by Rutherford's scattering experiment, we need to analyze the key findings of the experiment. Here’s a step-by-step breakdown:

### Step 1: Understanding Rutherford's Experiment
Rutherford conducted an experiment where he bombarded a thin gold foil with alpha particles. He observed how these particles scattered, which led to significant conclusions about the structure of the atom.

**Hint:** Recall the setup of Rutherford's experiment and what he was trying to discover about atomic structure.

### Step 2: Key Observations from the Experiment
1. **Most of the atom is hollow**: Rutherford concluded that since most alpha particles passed straight through the gold foil with little deflection, the majority of the atom is empty space.

2. **Alpha particles suffer negligible deflection by electrons**: Given the high mass and charge of alpha particles, they were found to be deflected mainly by the nucleus rather than by electrons, which are much lighter and less influential in terms of scattering.

3. **Very few particles bounce back**: Rutherford noted that only a small fraction of alpha particles were deflected back at large angles, indicating a dense nucleus at the center of the atom.

**Hint:** Think about the implications of alpha particles bouncing back and what that indicates about the atomic structure.

### Step 3: Evaluating the Statements
Now, let's evaluate the statements provided in the question:

1. **Most part of the atom is hollow**: This statement is consistent with Rutherford's conclusion.

2. **Alpha particle due to its high mass and charge suffers negligible deflection by an electron**: This is also true, as alpha particles primarily interact with the nucleus rather than electrons.

3. **A very few particles bounce back on their original path**: This statement is true and reflects Rutherford's observations.

### Step 4: Identifying the Incorrect Statement
The question asks for the statement that was **not** proposed by Rutherford. Since all the statements provided are consistent with Rutherford's findings, we need to identify the one that does not align with the experiment's conclusions.

After careful consideration, the statement that does not align with Rutherford's conclusions is:

**"Most of the particles suffer significant deflection from their original path."**

This is incorrect because while some deflection occurred, most particles passed through with little to no deflection.

### Final Answer
The statement that was not proposed by Rutherford’s scattering experiment is: **"Most of the particles suffer significant deflection from their original path."**
