I could remeber during the 1890’s when I met this friend of mine who contributed a lot to the discovery and explanation of the atom, I call him J.J Thomson😋
J.J Thomson was a physicist who is credited for discovering the
electron.😙 He used his research on cathode ray tube technology in this
discovery.
CATHODE RAY TUBE (stop wondering. Antimony got you)
How does this Tube Work?🤔
1. Nearly Empty tube (Air has been sucked out)😉
2. An electric charge is passed through the tube. Travels from cathode to
anode😮
3. The charge is invisible, so to see where it traveled a fluorescent screen is
placed at back of tube. Where the beam hits, a
dot will appear on the screen. You could also use a
fluorescent gas and the whole tube will light up.😫
4. This beam will always travel straight if not
interfered with.😏
5. The deflection coils each have a specific charge.
One is positive and the other is negative.🤐
6. Thomson showed that
the charge would deflect away from the negative
coil. He then stated that this charge was thus a
negative charge.🤥
J.J Thomson was an excellent physicist and thus did not stop when he had found this negative
charge. Through a series of clever experiments he was able to predict the mass of this charge.
SCIENTIFIC INTERPRETATION AT ITS BEST😎😎😎
He then found out that this charge was 1000 times lighter that a hydrogen atom. He made a bold
statement saying that this negative charge must be inside an atom. This negative charge (he called
corpuscles) later became known as the electron. ( This guy self get time o😐. My devoted friend🤗
Now let's check the atomic model he postulated.
Using what he had discovered, Thomson predicted what an atom should look
like. These are the key points to Thomson’s Atomic Model: (note this😶
1. Because of its design this model is known as the plum
pudding model😁
2. Each atom is a sphere filled with positively charged
‘fluid’. This resembles the sticky jam part of a pudding.
3. Corpuscles (later called electrons), are the negatively charged particles
suspended in this ‘fluid’. This resembles the plums in the pudding.
4. He did not predict the movement of these electrons😉
Mr thompson was really great. I think HD loves plum pudding. He just gave a nice theory but let's continue the journey down to our present day model.🤐
