What was John Thomson's experiment for the modern model?
John Thomson's experiment involved studying the properties of cathode rays in a cathode ray tube. By observing the behavior of these rays in the presence of electric and magnetic fields, Thomson was able to determine the charge-to-mass ratio of the electron. This experiment provided important evidence for the existence of subatomic particles and laid the groundwork for the development of the modern atomic model.
Who said that 'atoms are negatively charged particles'?
It's J.J. Thomson He had the plum pudding experiment The answer is Thomson
Why do you think Thomson hypothesized that electrons must come from inside an atom?
Thomson had two pieces of evidence: 1- No matter what metal he used for the disk, the particles produced were indentical. 2- The particles had about 1/2000 the mass of a hydrogen, the lightest atom. These experiments provided the first evidence that atoms are made of even smaller particles.
How did Thomson experiment change Dalton atomic model?
John Dalton stated "all atoms of a given element are identical"; discovery of isotopes by Thomson infirmed this old hypothesis.
What particles did jj Thomson discover?
J.J. Thomson discovered the electron in 1897 while conducting experiments with cathode rays. This discovery was groundbreaking as it provided evidence for the existence of subatomic particles.
What evidence supported Thomson's hypothesis that negative particles he observed came from inside atoms.?

What experiment do Thomson do?
He hit plates with light

How did Thomson's experiment change Dalton's atomic model?
Thomson's experiment provided evidence for the existence of electrons within atoms, leading to the modification of Dalton's model to include subatomic particles. Instead of envisioning atoms as indivisible spheres, Thomson's discovery suggested that atoms were composed of smaller, negatively charged particles (electrons) embedded within a positively charged sphere.
Why was it important for Thomson to repeat his experiment?
Thomson did the experiment various times to observe if the particles behave the same way. How they did he determined they were the same kind later called electrons.
How did the Thomson's experiment change Dalton's atomic model?
Thomson discovered that the atom contained smaller particles called electrons
