J.J. Thomson's discovery of the electron through his cathode ray experiment discredited John Dalton's theory that atoms are indivisible and indestructible, as Thomson showed that atoms are composed of subatomic particles. This led to the development of the plum pudding model of the atom.
What else can I help you with?
How did atom research conducted by john Dalton sir Joseph john Thomson sir ernest Rutherford and niels bohr impact scientific thought throughout the history of science?
The atom research conducted by John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr contributed significantly to our understanding of the structure of the atom. Dalton proposed the atomic theory, Thomson discovered the electron, Rutherford formulated the nuclear model of the atom, and Bohr developed the planetary model of the atom. These discoveries paved the way for modern atomic theory and revolutionized our understanding of matter and chemical reactions.
John daltons inventions?
John Dalton was a British scientist known for his work in chemistry and the development of atomic theory. His most notable invention was the concept of atomic theory, which proposed that all matter is composed of tiny, indivisible particles called atoms. Dalton also introduced symbols to represent elements and their atomic weights, laying the foundation for modern chemistry.
Did John Daltons work lead to other important scientific discoveries?
Yes, John Dalton's work on atomic theory laid the foundation for modern chemistry and physics. His ideas paved the way for further research in understanding the nature of matter, leading to discoveries such as the periodic table of elements and the development of quantum mechanics.
Who are the scientist involve in the atomic theory?
Some of the key scientists involved in the development of atomic theory include John Dalton, who proposed the atomic theory in the early 19th century, J.J. Thomson, who discovered the electron, Ernest Rutherford, known for his gold foil experiment that led to the discovery of the nucleus, and Niels Bohr, who developed the planetary model of the atom.
Did Dalton discover electrons?
No, John Dalton did not discover electrons. The existence of electrons was proposed by J.J. Thomson in 1897 through his experiments on cathode rays. Dalton, on the other hand, is known for his work on atomic theory in the early 19th century.
Why was daltons model of the atom changed after Thompson experiment?
John Dalton's atomic theory indicated that atoms were indivisible spheres. When JJ Thomson did his work with cathode ray tubes, he discovered that atoms contain electrons, which meant that the atom is not indivisible, that there are smaller particles within
Who discovered the theory of electrons and quantum mechanics?
Joseph John Thomson, Max Planck
