What did James Chadwick use to discover neutrons?
James Chadwick used a series of experiments involving alpha particles and beryllium to discover neutrons in 1932. By observing the scattering of these particles, he was able to infer the existence of neutrons, which are electrically neutral particles found in the nucleus of atoms.
Did Thompson's experiment led to discovery of the neutron?
no
Did the Greeks discover particles?
Depends on what you mean by "discover". Around 450 BC, Democritus proposed his idea that matter was not infinitely divisible, but made of chunks called "atoms", which each had distinct properties that contributed to the properties of the whole material. This is pretty similar to the true state of affairs, but this was pretty much guesswork on his part. The Greeks never performed any kind of experiments that could confirm the existence of particles. People didn't really start observing particles like electrons until the latter half of the 19th century, although they had a rough idea that they had to exist prior to that. Protons and neutrons weren't observed directly until the 20th century.
How the 3 subatomic particles discover?
Subatomic particles were discovered through experiments involving the interaction of matter with various forms of radiation, such as beta particles, gamma rays, and alpha particles. Scientists like J.J. Thomson, Ernest Rutherford, and James Chadwick played integral roles in the discovery of electrons, protons, and neutrons, respectively. Their contributions to the field of atomic and nuclear physics helped unravel the nature of subatomic particles and their properties.
How did Thompson's model differ from Daltons model?
Thompson's model proposed that atoms were made up of positive and negative charges distributed throughout a positively charged sphere, similar to a raisin pudding. In contrast, Dalton's model suggested that atoms were indivisible and uniform spheres with no internal structure. Thompson's model introduced the idea of subatomic particles, while Dalton's model viewed atoms as simple building blocks of matter.

Which scientist used a cathode ray tube to discover negatively charged subatomic particles?
The scientist who used a cathode ray tube to discover negatively charged subatomic particles was J.J. Thomson.
What did James Chadwick use to discover neutrons?
James Chadwick used a series of experiments involving alpha particles and beryllium to discover neutrons in 1932. By observing the scattering of these particles, he was able to infer the existence of neutrons, which are electrically neutral particles found in the nucleus of atoms.
What did John Thompson discover?
J.J Thomson discovered Electrons which is the negatively charged sub-atomic particle of an atom
What Dalton discover?
Dalton discovered the particles that make the atom and the atom itself
