The first model of an atom was given by

Options

A. N Bohr
B. E Goldstein
C. Rutherford
D. JJ Thomson

Explanation

**Step-by-Step Solution:**

1. **Identify the Scientist**: The first model of the atom was proposed by J. J. Thomson.

2. **Understanding Thomson's Model**: According to J. J. Thomson, the atom is structured like a sphere that has a positive charge. Within this sphere, negatively charged electrons are embedded.

3. **Analogy Used**: Thomson used the analogy of a "plum pudding" to describe his model. In this analogy, the positively charged sphere represents the pudding, while the negatively charged electrons represent the plums scattered throughout.

4. **Significance of the Model**: This model was significant because it was one of the first to suggest that atoms are not indivisible but have internal structures.

5. **Further Developments**: Following Thomson, other scientists like Goldstein, who discovered protons, and Niels Bohr, who provided a more detailed model of the atom, contributed to our understanding of atomic structure.
