Question

which scientist developed the first model of the atom that proposed the structure of the inside of an atom? dalton bohr rutherford thomson

Explanation:

• Dalton: Proposed the atomic theory that atoms are indivisible and indestructible. But he did not propose the structure of the inside of an atom.
• Bohr: Proposed the Bohr model of the atom, which described electrons orbiting the nucleus in fixed - energy levels. But it was not the first model to propose the internal structure of an atom.
• Rutherford: Proposed the nuclear model of the atom (after the gold - foil experiment). But it was after Thomson's model.
• Thomson: Discovered the electron and proposed the "plum - pudding" model of the atom. In this model, the atom was thought to be a sphere of positive charge with negatively charged electrons embedded in it. This was the first model to propose the internal structure of an atom.

Answer:

Thomson
