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.
to make the experiment more reliable
It's important to repeat experiments so then you know that you did the experiment right.
Repeating the experiment will either confirm the results you've just obtained, or show up errors.
so others can repeat it and see if you did it right
To make sure your results are Valid/reliable. You should always repeat your experiments and if using times or amounts and in the future going to make a graph its best to do the experiment 3 times and calculate the average on place the average result on to your graph.

J. J. ThomsonJ. J. Thomson did the cathode ray experiment where he discovered the existence of electrons.

He hit plates with light
It's J.J. Thomson He had the plum pudding experiment The answer is Thomson
so others can repeat it and see if you did it right
He hit plates with light
He did nothing
A cathode ray
No
J.J. Thomson discovered the electron studying the deflection of cathode rays.
