Contributors to the Atomic Theory

John Dalton

1803

Proposed the atomic theory with spherical solid atoms based upon measurable properties of mass and that atoms are indivisible

Eugen Goldstein

1886

Created the term Cathode rays for the negatively charged electrons, and discovered anode rays, the positively charged particles

J.J. Thomson

1897

He discovered the electron by applying his own vacuum technique, and saying this matter being the substance from which all the chemical elements are built up

Ernest Rutherford

1899

Using the worlds most sensitive electromagnetic wave detector at that time he discovered two distinct radiations, which he named them alpha and beta rays (high speed electrons)

Max Planck

1900

He was the originator of the quantum theory, and explained the patteren of light intensity emmited from a black body at any given frequency. E=hv

Albert Einstein

1905

Developed his theory of relativity and photoelectric effect

Robert Millikan

1909

Discovered the charge of an atom in his 1909 oil drop experiments

Neils Bohr

1913

Explained that electrons traveled in fixed orbits around the nucleus and also explained how electrons gain and lose energy. He created the quantum theory.

Henry Moseley

1913

Determined the importance of the atomic number over atomic mass, in his Moseley Law, which correlated wavelength and atomic number

Louis DeBroglie

1924

He discovered the wave nature of electrons, that the particles can behave like waves, and the waves can behave like particles. L=h/(m•v)

Erwin Schrodinger

1926

He introduced the Schrodinger wave, which was the mathematical equation of wave mechanics that is still the most widely used piece of mathematics in modern quantum theory. It posits a non-relativistic wave equation that governs how electrons behave within the hydrogen atom.

Werner Heisenburg

1927

In his Uncertainty Principle it states that it is impossible to accurately measure both position and momentum at the same time, and that the more precisely we know an object's position the less precisely we can know its momentum, and vice versa.

James Chadwick

1932

He proved the existence of neutrons, and elemntary particle without any electrical charge and a building block of the nucleus
