Created the Law of Conservation of Matter
Created the Law of Definite Proportions
Organized the Atomic Theory and the Law of Multiple Proportions
Invented the battery, in 1800 an Italian built the first battery, a device that provided a steady current of electricity.
Passed electrical current through substances to decompose them. Isolated the elements Potassium, Magnesium, Strontium, Barium, and Calcium
Davy's protege, defined elctrolysis, electrolyte, electrodes, anode, cathode, ion, anion, and cation
Discovered Cathode Rays by charging the air inside a glass tube and finding green particles
Performed cathode ray tube experiment and discovered electrons
Discovered the proton, particles traveling in the opposite direction of the electrons in a cathode ray tube.
Performed the oil drop experiment in order to determine the mass and charge of electrons
(Wilhelm Conrad) Rotengen
Discovered the x-ray and x-rayed hand
Discovered that uranium salts emitted rays that produced an image on a photographic plate.
Performed high energy experiments that discovered neutrons
(Marie Sklodowska) Curie
A graduate student of Becquerel's. Coined the term Radioactivity. Worked with husband, Pierre, in isolating Polonium and Radium.
Defined alpha, beta, and gamma rays. Gold foil experiment proves there is a dense, positively charged nucleus
Created the planetary model of the atom
(Louis) de Broglie
Hypothesized that matter behaves like a wave, and developed an equation to calculate the wavelength of every object
Gave rise to the Quantum Mechanical Model with his calculations of the probability of where an electron could be found at a around an atom at a given time.
