Which scientist developed the first model of the atom that proposed the structure of the inside of an Dalton Bohr Rutherford Thomson

## Step 1<br />The question asks us to identify the scientist who developed the first model of the atom that proposed the structure of the inside of an atom. The options provided are Dalton, Bohr, Rutherford, and Thomson.<br /><br />## Step 2<br />John Dalton is known for his atomic theory, which proposed that matter is composed of atoms of different weights. However, his model did not delve into the internal structure of the atom.<br /><br />## Step 3<br />Niels Bohr is known for his model of the atom, which proposed that electrons orbit the nucleus in specific energy levels. However, this model did not provide a detailed structure of the inside of the atom.<br /><br />## Step 4<br />Ernest Rutherford is known for his gold foil experiment, which led to the discovery of the nucleus. However, his model did not provide a detailed structure of the inside of the atom.<br /><br />## Step 5<br />J.J. Thomson is known for his model of the atom, which proposed that atoms are composed of a positively charged sphere with negatively charged electrons embedded in it. This model, known as the "plum pudding" model, was the first to propose a structure for the inside of an atom.
