J.J. Thomson discovered electrons are negative by conducting experiments with cathode rays in vacuum tubes. He observed how the rays were attracted to a positively charged plate, leading him to conclude that the particles in the rays carried a negative charge, which he named electrons.

When did JJ Thomson discover the electron?
J.J. Thomson discovered the electron in 1897 while conducting experiments on cathode rays. He observed that these rays could be deflected by electric and magnetic fields, leading him to propose the existence of a negatively charged particle within the atom, which he named the electron.
How did jj Thomson figure out his theory?
J.J. Thomson discovered the electron through his experiments with cathode rays in a vacuum tube. By measuring the charge-to-mass ratio of the electrons, he concluded that they were fundamental particles. This led to the development of the plum pudding model of the atom.
Why did jj Thomson do his experiment?
J.J. Thomson performed his experiment to discover the existence of subatomic particles known as electrons. By studying the properties of cathode rays, he was able to determine the charge-to-mass ratio of electrons and propose the plum pudding model of the atom.
What is JJ Thomson model called?
The JJ Thomson model is called the "plum pudding model." It suggests that atoms consist of a diffuse positive charge with negatively charged electrons embedded within it, similar to plums within a pudding.
What were JJ Thomson's discovery?
J.J. Thomson discovered the electron in 1897, showing that atoms were made up of smaller particles. This led to the development of the plum pudding model of the atom. He also measured the charge-to-mass ratio of the electron.
What did Thomson discover in the atom?
JJ Thomson discovered electrons, which showed that atoms are not indivisible.
Who discovered electrons blue berry muffin model of atoms?
JJ Thomson
Who discovered negatively charged electrons using a cathode ray tube?
JJ Thomson.
What kind of father in science jj Thomson?
He discovered electrons, isotopes, and invented the mass spectrometer.
Did jj Thomson perform an experiment proving an atom has two parts?
yes, he discovered electrons.
What experimrents did jj Thomson?
After experiments with cathode rays Thomson discovered that these rays are deflected in an electrical field; and from this he proposed the existence of electrons.
The electron was discovered by who?
JJ Thomson

JJ Thomson, who discovered the electron.
What were JJ Thomson's contribution to chemistry?
ELECTRONS
Who discovered anode and cathode rays?
Cathode rays were discovered by JJ Thomson and carry a negative charge Anode rays were discovered by Goldstein and carry a positive charge.
Who performed an experiment with cathode ray tubes?
J. J. ThomsonJ. J. Thomson did the cathode ray experiment where he discovered the existence of electrons.
