Dalton's second theory was disproved by j.j. Thompson and ernest rutherford because dalton did not do any experiment to came out with that's theory,that is the reason why they came out with cathode ray tube and gold fuil apparatus.

What is Thomson Rutherford experiment?

The Thomson-Rutherford experiment refers to the groundbreaking work by J.J. Thomson and Ernest Rutherford that contributed to the understanding of atomic structure. Thomson's experiments with cathode rays led to the discovery of the electron, establishing that atoms are composed of smaller particles. Rutherford later conducted his famous gold foil experiment, which revealed that atoms have a small, dense nucleus surrounded by electrons, leading to the nuclear model of the atom. Together, their findings significantly advanced atomic physics and chemistry, reshaping the concept of atomic structure.


Who discovered that atoms contain subatomic particles?

J.J. Thomson discovered the first subatomic particle, the electron, in the late 19th century through his experiments with cathode rays. This discovery led to the understanding that atoms contain subatomic particles.


What did ernest Rutherford?

Ernest Rutherford is perhaps best known for his model of the atom. He developed his own model, based upon his research, to replace Thomson's plum-pudding model.


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.

Was neils bohr jj Thomson's student?

No, Niels Bohr was not J.J. Thomson's student. Niels Bohr was a student of Ernest Rutherford, who was a colleague of J.J. Thomson. Bohr developed his own atomic model, known as the Bohr model, which built upon the work of Thomson and Rutherford.
