The first model of atom in 1998 was proposed by

Options

A. Ernst Ruterford
B. Albort einstein
C. j.j thomson
D. neiels bohr

Explanation

To solve the question regarding who proposed the first model of the atom in 1998, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Year**: The question specifies the year 1998. However, it is important to note that the first model of the atom was not proposed in 1998, but rather earlier in history.

2. **Recall Historical Models**: The first significant model of the atom was proposed by John Dalton in the early 19th century. However, the question likely refers to a more modern interpretation or model that may have been revisited or modified in 1998.

3. **Identify the Correct Scientist**: The model that is often referenced in discussions of atomic structure is the Plum Pudding Model proposed by Sir J. J. Thomson in 1897. This model describes the atom as a sphere of positive charge with negatively charged electrons embedded within it.

4. **Clarify the Confusion**: If the question is indeed about a model proposed in 1998, it may refer to a specific modern interpretation or advancement in atomic theory. However, based on the context provided in the video transcript, it is clear that the Plum Pudding Model by J. J. Thomson is the focus.

5. **Conclude the Answer**: Therefore, the answer to the question is that the first model of the atom, often referred to in this context, was proposed by Sir J. J. Thomson.

### Final Answer:
The first model of the atom was proposed by Sir J. J. Thomson.
