This picture comes from: [] Name: Niels Bohr DOB-DOD: Oct. 7th, 1885- November 18th, 1962 Country of origin: Copenhagen, Denmark

Niels Bohr was born in Copenhagen, Denmark October 7th 1885. His father was a professor of Physiology, and pushed his son's genius into the field of Physics. He attended Copenhagen University, and pursured his doctorate degree in physics. He went on to Cambridge and studied alongside JJ Thomson. After this part of his life Bohr he went on to study the atomic structure on the basis of Rutherford's discovery of the atomic nucleus. This prompted his contribution to the atomic structure.

Bohr's contribution to the atomic structure was he developed an explanation of atomic structure that underlies regularities of the periodic table of elements. His atomic model had atoms built up of sucessive orbital shells of electrons.

This picture comes from: [] Name: Erwin Shrodinger DOB-DOD: August 12, 1887- Jan. 4th 1961 Country of Origin: Vienna, Germany

Erwin Schrödinger was born on August 12, 1887, in Vienna. In 1898 he attended the Arkademisches school.Schrödinger studied in Vienna under Franz Exne and Hasenohrl. In 1911, Schrödinger became an assistant to Exner. In 1926 Shrodinger came up with the Shrodinger equation which is an equation that describes how the quantum state of a physical system changes in time. It is as important to quantum mechanics as Newton's Laws are to modern mechanics. He remained interested in atomic physics and disliked the accepted dual description in terms of waves and particles. Therefore he came up with his own theory which greatly impacted and influenced the atomic structure.

Shrodinger's contribution to the atomic structure was he viewed electrons as continuous clouds and introduced wave mechanics as a mathematical model of the atom

This picture comes from: [] Name:James Chadwick DOB-DOD: Oct. 20th 1891- July 24th 1974 Country of origin: Chesire, England

James Chadwick was born in Chesire England, and attended Manchester University in 1908. He spent two years working under Professor Rutherford in the physical laboratory in Manchester. Rutherford has succeeded that year in disintergrating atoms by bombbarding nitrogen with alpha particles with the emission of a proton. This was the first artificial nuclear transformation. Chadwick's claim to fame arose in 1932 when he discovered the neutron.

James Chadwick's contribution to the atomic structure is a major one, because by using alpha particles discovered a neutral atomic particle with a mass close to a proton. This ended up being the discovery of the neutron.
