-
He first proposed the existance of an ultimate particle.
-
Proposed an "atomic theory" with spherical solid atoms based upon measurable properties of mass.
-
Proposed the perodic law asnd developed the first periodic table
-
Studied "canal rays" and found they were associated with the proton H+ .
-
Determined the unit of charge of the electron
-
publishes his atomic theory describing the atom as having a central positive nucleus surrounded by negative orbiting electrons.
-
Discovered Moseley's law is an empirical law concerning the characteristic x-rays that are emitted by atoms.
-
He is best known for his uncertainty principle, which restricts the accuracy with which some properties of atoms and particles--such as position and linear momentum--can be determined simultaneously
-
discovered a third type of subatomic particle, which he named the neutron.
-
Edwin Schrodinger stated that rather than electrons being distributed within an electron configuration of shells and energy levels, they were arranged in orbitals which were systematically distributed within Electron Clouds.
