He hit plates with light
A cathode ray
J.J. Thomson discovered the electron studying the deflection of cathode rays.
all atoms contain the same particle that produces the ray.
Don't know can you help me please
He sent a cathode ray between electrically charged metal plates.
J. J. ThomsonJ. J. Thomson did the cathode ray experiment where he discovered the existence of electrons.
It's J.J. Thomson He had the plum pudding experiment The answer is Thomson
He hit plates with light
A cathode ray
He did nothing
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.
J.J. Thomson discovered the electron studying the deflection of cathode rays.
i dont know the answer
Thomson discovered that the atom contained smaller particles called electrons
J.J Thomson conducted the cathode-ray tube experiment in 1911.
Cathode Rays
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.
