PRESENTATION OUTLINE
Who was he? Fredrick Soddy was an English radiochemist who worked with Ernest Rutherford to discover isotopes.
What did he discover?
Frederick Soddy discovered the concept that atoms can be identical chemically but also have different weights. These atoms were called isotopes. A word made up by Frederick Soddy meaning equal or same place.
What tools did Frederick Soddy use?
Frederick Soddy used the rather basic tools that were available to him. He used hand blown glass bulbs, carefully made and then evacuated to create a vacuum tube. Soddy used a radium sample sealed inside a thin glass container. This was sealed inside an evacuated tube. The evacuated tube should have remained entirely empty if most elements were in the inside container.
How was what Soddy discovered different to others?
What Soddy discovered was completely unique to what any other scientists had came up with simply because no one had ever came up with a similar theory. He was the first person to ever discover isotopes.
