Found that matter is made of tiny invisible particles in different formations, and he named them atoms. -
"Proposed" that tiny solid particles that kept moving made up the universe.
-
Created a theory stating that atoms were spheres with measurable properties of mass.
-
Found that magnetic and electric fields filled space in the atom.
-
Proposed that the electricity was made from, what he named, electrons.
-
Discovered the electron by using a cathod ray tube.
-
Created the "Saturnian" model of an atom.
-
Used the oil drop experiment to find the charge and mass of an electron.
-
Used the gold foil experiment to discover the almost solid, positively charged nucleus. Made the planetary model.
-
He used X-ray tubes to find the charge of the nuclei of atoms, and he said that the atomic number is equal to the number of protons.
-
Produced alpha particles by building a linear accelerator that shot protons at lithium.
-
Found that electrons were in a cloud and came up with an equation - wave mehcanics - to explain them.
-
Suggested that there were anti-particles in an atom, and found the pistron (first anti-electron).
-
Discovered the neutron using alpha particles and came up with a model for the atom.
-
Created the Bohr model of an atom.
