Determined that all matter was formed of different particles and the properties of said particles determined the properties of matter. Democritus is known as the "laughing philosopher" because he emphasized the value o cheerfulness. -

Established that atoms of different elements could be distinguished by their varying atomic weights. He became the first scientist to explain behavior of atoms in the measurement of their weight and he is also known to have established that atoms cannot be created nor destroyed (discovered 1803-1808) John Dalton was a Quaker. -
Thomson is said to have discovered atoms by performing an experiment involving cathode rays established that electrons are part of atoms. JJ Thomson was knighted in 1908 -

Using the "falling-drop method" Robert discovered the accurate determination of an electron's charge Robert Millikan sophomore year in college he asked to teach a intro level of physics. -
Discovered the nucleus of the atom Ernest won the Nobel Prize for chemistry in 1908 -

Proposed a theory for the hydrogen atom. His theory stated that electrons move in predetermined orbits nd by jumping to a lower level produces radioactivity Niels Bohr was born and raised in Copenhagen. -

Heisenberg formatted the quantum mechanics. He had a gift when it came to playing piano. -
-
Developed a powerful model of the atom. Schrodinger combined the equations for the behaviors of waves with the de Broglie equation which demonstrated the mathematical model for the distribution of electrons in an atom A moon crater is named after him -
In short, he discovered the neutron. James was a prisoner of war in WWI. -
