Discovery of Electrons
The basic idea of the discovery of the elementary particles was generated by Dalton’s Atomic Theory. John Dalton in 1808 gave the first scientific theory about atoms, in which, he stated that atoms are the smallest particle of any matter.
How did j.j. thomson discover electrons
They are indivisible and indestructible. According to Dalton Atomic Theory:
- Matter consists of tiny indivisible particles called Atoms.
- Atoms can neither be created nor be destroyed.
- Atoms of the same element are alike in all respect but they differ from the atoms of the different elements.
- Atoms of an element combine in a simple whole-number ratio to form molecules.
The above statements are called the Postulates of Dalton’s Atomic Theory.
But, later these postulates were proved wrong as the first indication of sub-atomic particles came due to the study of static electricity by Faraday which says that the flow of electricity is caused by due to the charged particles.
Sir J.
J. Thomson first proved the existence of negatively charged particles within an atom called electrons. Thus, the el
