Introduced "wave" mechanics to the atomic level, creating the Wave Model. Electrons are described by orbitals, standing probability waves. In the Wave Model of the Atom, the electrons in the atom have discrete energies and obey the Exclusion Principle. 2.
-
1766-1844 Lived in England. He proposed an atomic theory with spherical solid atoms based upon measurable properties of mass. He also created the Billiard Ball model.
-
Discovered canal rays, or the positive protons in atoms through a neon light and a magnet. He found that they relate to H+ and atoms have mass in the vacuum ray.
-
1871-1937 Cambridge England.Studied radiations emitted from uranium and named them alpha and beta.He estimated atom size and concluded mass was concentrated in the nucleus.
-
Discovered the decay of Uranium releases radioactivity, and she and her husband found Polonium and Radium. first person ever to be awarded two Nobel prizes.
-
Invented the quantum theory in 1900 that had particles that are individually charged inside the atom. Based on the probability, that each electron is individually charged and follow an orbital path.
-
The Plum Pudding Model was created by JJ Thompson.the model represented an attempt to consolidate the known properties of atoms at the time
-
Published e=mc^2. Created the planetary model and got famous for it.
-
Found the charge of an electron using the equation: (e=1.602 x 10 -19 coulomb) and the mass (m = 9.11 x 10 -28 gram).
-
It was discovered by Ernest Rutherford. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure.
-
Neihls Bohr created it. Energy is transferred only through well defined quantities. He put a gold sheet in the middle of a big ring and shone a light through it.
-
Neihls Bohr created the elemental model. The model represents how many neutrons protons and electrons are in the atom. He used small solid balls to prove this
-
Successive orbital shells of electrons around a nucleus. Found by measuring charge put out by atoms in a vacuum tube.
-
It was created by Joseph Lucas is a physical model that shows where electrons are located throughout the volume of the atoms.The Lucas model also predicts the structure of the nucleus and correctly predicts hundreds of nuclide spins.
