Streams of negatively charged particles, known as electrons, were first observed by British physicist J.J. Thomson in 1897. His experiments with cathode rays demonstrated that these particles were much smaller than atoms and had a negative charge. This discovery was pivotal in the development of atomic theory and led to the understanding of the structure of atoms.
What else can I help you with?
What causes solar storms?
Solar winds are caused by charged particles that are ejected into the upper atmosphere of the sun. The sun continues to make these streams of charged particles and sending them into space.
Streams charged particles coming from the sin make the solar?
They make up part of the solar wind
What experiment evidence did Thomson use to support his hypothesis that atoms are made up of even smaller charged particles?
J.J. Thomson used cathode ray tube experiments to support his hypothesis that atoms contain smaller charged particles. He observed that cathode rays, which were streams of negatively charged particles (later known as electrons), were deflected by electric and magnetic fields, indicating that they had mass and charge. This led him to conclude that atoms were not indivisible, as previously thought, but instead composed of smaller charged components. His work ultimately contributed to the development of the "plum pudding" model of the atom.
What are chimney or ducts that's have electrically charged parts inside them?
Electrostatic precipitators are devices used in chimneys or ducts with electrically charged parts inside to remove solid particles, like dust and ash, from gas streams. As the gas passes through the device, charged particles are attracted to collection plates with the opposite charge, allowing clean gas to exit the system.
Is cathode rays are material particles?
Cathode rays are streams of electrons that travel from the negatively charged cathode to the positively charged anode in a cathode ray tube. They are not material particles in the traditional sense because they do not have mass or volume, but rather behave as electron beams.
What are streams of electrically charged particles sent out by the corona?
They are protons.
What was J J Thompson's hypothesis when he observed that rays bend toward a positively charged plate and give a negative charge to objects they strike?
He hypothesized that cathode rays are streams of electrons or negative charges
How did Thomson know that atoms must contain particles with positive charges?
He knew that in a vacuum tube metals can be made to emit streams of negative charge which were then called cathode rays. If atoms are neutral and can produce negative charge, there must be positive charge there too.
What causes solar storms?
Solar winds are caused by charged particles that are ejected into the upper atmosphere of the sun. The sun continues to make these streams of charged particles and sending them into space.
Streams charged particles coming from the sin make the solar?
They make up part of the solar wind
What are streams of charged particles ejected from the sun?
Streams of charged particles ejected from the sun are called solar wind. These particles consist mostly of electrons and protons that are continuously emitted from the sun's outer atmosphere, known as the corona. Solar wind can interact with Earth's magnetic field, producing phenomena such as auroras.
What are loops of matter flowing from the Sun called?
The streams of charged particles flowing out into Space from the Sun are collectively the Solar Wind.

Streams of protons and electrons emitted from the Sun produce?
Streams of protons and electrons emitted from the Sun produce solar wind, a continuous flow of charged particles that sweep through the solar system. These particles can interact with the magnetic field of Earth, causing phenomena such as auroras and geomagnetic storms.
Are alpha rays charged?
Yes. Alpha rays are streams of alpha particles (helium nuclei), each of which carries 2 times the charge of a proton. In S.I. units the alpha particle's charge is +3.2 x 10-19 Coulombs, to two significant figures.
