Chapter 1, question 19, asks us about the contributions of j .j.
00:05
Thompson and ernest rutherford in our understanding of the structure of an atom.
00:10
So let's consider what each of these two scientists discovered about atomic structure.
00:16
First, let's look at j .j.
00:18
Thompson.
00:19
His experiments discovered the electron, and he experimented with what's called a cathode ray tube.
00:27
This tube essentially shoots atoms through an electromagnetic, field and he found that there were positively charged molecules inside of the atom.
00:37
So his theory was that essentially an atom is a circular shape where the whole thing is roughly positively charged and you have little circles of negative charge.
00:52
He called this the plum pudding model because it looks a bit like plum pudding...
