J.J. Thomson discovered the electron in 1897. In 1904, he proposed a model of an atom, describing that there was an equal distribution of negative and positive charges throughout the atom. In 1909, Ernest Rutherford tested J.J. Thomson’s model by shooting positive particles at gold foil. Based on Thomson's model, it was predicted that the particles would fly through the foil with a small amount deflected back. Analyzing the results, Rutherford discovered that more of the particles bounced back than expected. Which of the following best explains how the results of Rutherford’s experiment affected Thomson’s widely-accepted atomic model?
A. Rutherford’s results were invalidated and discarded because Thomson’s model was correct.
B. Rutherford’s results supported parts of Thomson's model, but also provided new data and interpretations.
C. Rutherford’s results suggested that the model proposed by Thomson was based on false research and required a change in his hypothesis.
D. Rutherford’s results supported Thomson’s model that there was a negative core surrounded by positive charges and caused a modification in the overall atomic theory.

this is a lot to read but it’s definitely C! Rutherford’s results suggested that the model proposed by Thomson was based on false research and required a change in his hypothesis. thank make me brainlest

Rutherford's results declined the results of Thomson's model, the correct option is C.

What are Atomic models?

Atomic Models are the scientific theories proposed to determine the structure of an atom.

There are mainly 5 theories proposed for atomic models.

1. John Dalton's Atomic Model: An atom is the basic building block of all physical entities in the universe.

2. Plum Pudding Model, created by J.J. Thomson, uses the comparison of plum pudding, where the positive charge is uniformly dispersed throughout and the negative charge is randomly sprinkled on top, to explain how subatomic particles are structured.

3. Rutherford's model: proved the presence of a nucleus.

4.Niel Bohr's model: Arrangement of electrons in shells.

5. Erwin Schrodinger's model is also called as Quantum Model.

In J.J. Thomson's model, the equal distribution of positive and negative charges is proposed while,

Rutherford's theory declines this arrangement and proposes that the positively charged nucleus occupies a very small part and there is empty space in the atom.

So, Rutherford’s results suggested that the model proposed by Thomson was based on false research and required.
