Note: I had to remake my blog and this post got deleted. I just noticed this yesterday, so thats why this is posted so late.

The first great discovery of chemistry was in the later part of the 1800 century was made by Preistly. This had to do with gases. Preistly went to Paris to talk with another great chemist.

List of elements made by Preistly.

Second discovery was made by John Dalton, which was the first person that "discovered" atoms. He made a new system called the Atomic Theory.

Turn of 1900th century. Davey discovered how electricity reacted to different chemicals and change them.

Bunson and Kurkofe built a spectroscope where they could see what atoms were present. They were able to discover two more elements. They ended up using their machine to discover that their was sodium in the sun.

Joseph Thompson discovered electrum. He used a crook’s tube in his expiriments to study small parts of atoms.

The discovery of how atoms of one element combined with atoms of another element was discovered by Gilbert Newton Lewis. This led to scientists starting to make chemical compounds.

X-rays were the start of this discovery. Over the decades, scientists started making break throughs.

Bekrel discovered that uranium emitted x-rays by using the photo paper. The Curies then took up the project and in the process, discovered two new elements in the process.

John Hyatt made the first plastic, and led the discovery of different plastics.

Nanotubes where discovered by Richard Smallway and a team of scientists. Nanotubes are a cluster of carbon atoms.
