What did ernest Rutherford and jj Thomson do together?
Ernest Rutherford and J.J. Thomson worked together on research related to the structure of the atom. Thomson discovered the electron and proposed the plum pudding model of the atom, while Rutherford conducted the famous gold foil experiment that led to the discovery of the atomic nucleus. Their work laid the foundation for modern atomic theory.
How did Ernest Rutherford discovery change JJ Thomson's theory?
Ernest Rutherford's discovery of the atomic nucleus through his gold foil experiment fundamentally changed J.J. Thomson's plum pudding model, which posited that atoms were composed of a diffuse cloud of positive charge with negatively charged electrons embedded within it. Rutherford's findings revealed that atoms consist of a dense, positively charged nucleus surrounded by orbiting electrons, suggesting that most of the atom's volume is empty space. This led to the development of the nuclear model of the atom, significantly altering the understanding of atomic structure. Ultimately, Rutherford's work laid the groundwork for modern atomic theory, moving beyond Thomson's initial concept.
How did Rutherford's idea differ from Thomson's idea?
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
How have scientists like JJ Thomson Ernest Rutherford and Niels Bohr helped to change and improve your scientific understanding of the atom?
Scientists like JJ Thomson, Ernest Rutherford, and Niels Bohr were pioneers in advancing our understanding of the atom. Thomson discovered the electron and proposed the plum pudding model, Rutherford conducted the gold foil experiment leading to the discovery of the atomic nucleus, and Bohr introduced the idea of quantized electron energy levels and the planetary model of the atom. Together, their contributions laid the foundation for modern atomic theory and our understanding of the structure of atoms.
How did Rutherford's theory change Thomson's theory?
Rutherford's theory significantly altered Thomson's earlier model of the atom by introducing the concept of a dense, positively charged nucleus at the center, surrounded by orbiting electrons. While Thomson's "plum pudding" model suggested that electrons were scattered within a diffuse cloud of positive charge, Rutherford's gold foil experiment demonstrated that most of an atom's mass and positive charge is concentrated in a small nucleus. This shift paved the way for the modern understanding of atomic structure, emphasizing the nucleus's role and leading to the planetary model of the atom.
How did the discovery by Rutherford change Thomson's theory?
Rutherford's discovery of the nucleus in an atom challenged Thomson's "plum pudding" model, which suggested that the positive charge and electrons were dispersed evenly throughout the atom. Rutherford's experiment showed that the positive charge was concentrated in a small, dense nucleus, with electrons orbiting around it. This led to a new understanding of the atom's structure and the development of the nuclear model.
How was Thomson's atomic theory differ from Rutherford atomic theory?
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
How did the discovery of the nucleus change Thomson's theory?
The discovery of the nucleus showed that atoms are not indivisible as Thomson had previously suggested. It led to the development of the new atomic model proposed by Rutherford, which included a dense, positively charged nucleus at the center with electrons orbiting around it. This model replaced Thomson's "plum pudding" model of the atom.

How did Thomson discovery change Dalton's atomic theory?
Thomson's discovery of the electron showed that there were things smaller than the atom that could be removed from the atom. Therefor the atom was not an "uncuttable" object as Dalton had proposed.
How did Ernest Rutherford discovery change JJ Thomson's theory?

How did J J Thomson discovery change Dalton's theory?
J.J. Thomson's discovery of the electron showed that atoms were not indivisible as Dalton thought, but were made up of smaller subatomic particles. This led to the development of the plum pudding model of the atom, which replaced Dalton's solid indivisible atom theory.

Who made the contributations to the theory?
Leukippus, Democritus, Dalton, Bohr, Rutherford, Thomson and many others.
What was the name of the discovery that disproved Dalton's theory?
Thomson disproved Dalton's theory because he discovered electrons.
