-Shot small positively charged alpha particles at a sheet of gold foil. In this experiment, Rutherford demonstrated that the atom has a tiny and heavy nucleus
-Designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure
-Concluded that atoms consisted largely of a lot of space with just a few electrons and most of the mass was concentrated towards the center, nucleus]]> 2017-10-18 14:02:59 UTC https://padlet.com/asdavis1/oi9e4h3auyx9/wish/198237889 Thomson 1521240 https://padlet.com/asdavis1/oi9e4h3auyx9/wish/198237964 First person to discover the electron. ]]> 2017-10-18 14:03:04 UTC https://padlet.com/asdavis1/oi9e4h3auyx9/wish/198237964 J.J.

3.   He discovered that atoms were mostly full of empty space.
4. He discovered the atoms and was the world's first successful alchemist (conversion of nitrogen into oxygen)
If he is to atom then Darwin is Evolution

Thomson. Provided the first hint that atoms were made up of smaller particles.
Theory
Atoms were made up of a positively charged substance with small, scattered, negatively charged electrons inside it.
Experiment
He studied the passage of an electric current through a gas. As that current passed through that gas, it gave off a ray of negatively charged particles. This was surprising because atoms had no charge.
Conclusion
The negative charges must have come from within the atom. That  meant that there has to be a smaller particle within the atom. Since the gas was a neutral charged gas, that meant that if there were negatively charged particles then there must be positively charged particles as well.
Thomson actually never found those positively charged particles.]]> 2017-10-18 14:05:13 UTC https://padlet.com/asdavis1/oi9e4h3auyx9/wish/198239529 John Dalton 1504578 https://padlet.com/asdavis1/oi9e4h3auyx9/wish/198239697 John Dalton discovered that all elements were made up of molecules, and each part of a molecule is an atom.

He won the nobel prize for his discoveries.
