Hi there.

Thompson conducted experiments using cathode ray tubes and electric fields.
00:11
And what he noticed is that there were particles produced.
00:16
It was not a beam of light, but it was a beam of particles.
00:25
And that beam bent away from the negative plate, so the negatively charged plate, and tore a positive plate.
00:55
So that's just a quick synopsis, quick summary of what he did with his cathode ray tubes, but more importantly, what it showed him was that there are particles smaller than the atom.
01:18
And these particles must be negatively charged.
01:32
And these particles, of course, were said to be what we now call electrons.
01:41
Okay, so two ways in which his research.
01:45
Changed the understanding of the atom.
01:49
One of them, it showed that atoms can be divided into smaller parts...
