John Dalton Research Paper

As Dalton discovered the atomic theory, J.J. Thompson was able to use the information to later on discover electrons.

J.J. Thompson discovered electrons when he was working on his cathode rays. He discovered that when voltage is applied across the electrons, the cathode rays are generated which creates a glowing patch that strikes the glass at opposite ends of the bottle. Through his experiments Thompson was able to discover that the rays were able to be deflected by an electric field. These were later on known as electrons.

Dalton’s atomic theory was changed when he thought that the atoms were indivisible particles, thus eventually Thompson’s discovery of the electron proved the existence of the subatomic particles.

Dalton’s atomic theory

At the age of 71 John Dalton , had a small stroke, a year later he had a second stroke that was more significant and he was unable to speak. In 1844 , Dalton experienced yet another stroke and on July 27th,1844 he died at the age of 77.

Dalton was born into a Quaker family. As Quakers were Christian, they were seen as dissenters who were established by the Church of England . As a result Dalton’s educational opportunities were restricted.

After 10 years of teaching at a Quaker boarding school , Dalton got a teaching position in the city of Manchester .

John Dalton joined the Manchester Literary and Philosophical Society, which provided him with laboratory facilities and an intellectual environment.

Dalton arrived at his view of atomism by way of meteorology. He kept a daily weather records book from 1787 until the day he
