Who discoverd the electron?
Answer:
J.J. Thompson, in 1897.
A Brit I think. Thompson?
Yes.

J.J. Thompson decided to find out for sure. Thomson was a physics professor at Cambridge University in the UK. He placed cathode tubes in electric and magnetic fields. He knew that these fields will move particles from side to side, but don't have much effect on how a wave moves. In his experiments, the cathode rays bent over to one side, so Thomson knew the cathode rays must be made of some small particle, which he dubbed a "corpuscle."
An Electron
Electrons are negatively charged particles that surround the atom's nucleus. Electrons were discovered by J. J. Thomson in 1897.
I used to know them by heart. Oh well. :)
The accreditation is given to J J Thompson.

O ne hundred years ago, amidst glowing glass tubes and the hum of electricity, the British physicist **J.J. Thomson **was venturing into the interior of the atom. At the Cavendish Laboratory at Cambridge University**, Thomson was experimenting with currents of electricity inside empty glass tubesHe was investigating a long-standing puzzle known as "cathode rays." **
Thomson's speculation was not unambiguously supported by his experiments. It took more experimental work by Thomson and others to sort out the confusion. The atom is now known to contain other particles as well. Yet Thomson's bold suggestion that cathode rays were material constituents of atoms turned out to be correct. The rays are made up of **electrons**: very small, negatively charged particles that are indeed fundamental parts of every atom.
