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.
What else can I help you with?
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?
He discovered the electron in a series of experiments designed to study the nature of electric discharge. Of course, this is only the discovery he is most known for. He had many other discoveries as well. Hope this helped! =) Here's a website that may be helpful to you: http://www.chemheritage.org/classroom/chemach/atomic/thomson.html
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?
J.J. Thomson, also known for discovering the electron, also proposed a model of the atom in 1904. This model is known as both the plum pudding model and the blueberry muffin model, and it posits that the atom is made up of electrons which are surrounded by a "pudding" of positive charges.
What were JJ Thomson's discovery?
J.J. Thompson worked to develop the atomic theory. He discovered that atoms have separate negative and positive material. Before him, it was widely believed that atoms were just spheres of matter.
What did Thomson discover in the atom?
JJ Thomson discovered electrons, which showed that atoms are not indivisible.

Did jj Thomson perform an experiment proving an atom has two parts?
yes, he discovered electrons.
What kind of father in science jj Thomson?
He discovered electrons, isotopes, and invented the mass spectrometer.
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.

JJ Thomson, who discovered the electron.
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?
