Niels Bohr (1885- 1962) received the Nobel Prize in physics in 1922 for the quantum mechanical model. Niels Bohr was a scientist who contributed his knowlege about the discovery of atom. Niels Bohr was born on Oct. 7, 1885 in Copenhagen, Denmark, one of his greatest discoveries was the Bohr model that he discovered when he was twenty-seven years old and that model was named after him. He also discovered the Quantum Theory with explained the properties of the metals with the aid of the electron theory.

Niels Hendricks David Bohr was born on October 7, 1885 in Copenhagen, Denmark. <ref> Msn 1997-2008.Neils Bohr. Msn Encarta. Jan. 23, 2009. </ref>. As Niels grew up, his family had great influence on his interest in education. His father, Christian Bohr was a professor of physiology at Copenhagen University and was known for his work on physical and chemical aspects of respiration <ref> Msn 1997-2008. Niels Bohr. Msn Encarta. Jan. 23, 2009. </ref>. Due to such atmosphere, he quickly developed an interest in physics <ref>Encyclopedia Britannica. 2009. Niels Bohr. Encyclopedia Britannica. Jan. 23,2009.</ref>.
In 1880 Christian Bohr recieved a doctoral in physics. <ref>School of Mathematics and Statistics at the University of St. Andrews, Scotland</ref> Later that year he married Ellen Adler, her father was a Jewish politician. <ref>Source: School of Mathematics and Statistics at the University of St. Andrews, Scotland</ref>. Ellen had three kids, the first was jenny whos Neils older sister. she was born in the manison her grandfather David Adler owned in 1883.<ref> School of Mathematics and Statistics at the University of St. Andrews, Scotland</ref>. When David Adler died Ellens mother still satyed at the castle house but Ellen went back to her mothers house and gave birth to Neils.<ref>School of Mathematics and Statistics at the University of St. Andrews, Scotland</ref>. When neils was still a baby his dad got a job opening in the Copenhagen University because a man named Peter Panum died so Christian became the new lecturer. his family moved into the professiral house of Panums.<ref>School of Mathematics and Statistics at the University of St. Andrews, Scotland</ref>. Than Niels little brother was born , he grows up to be a famous mathematician.<ref>Source: School of Mathematics and Statistics at the University of St. Andrews, Scotland</ref>.
Niels Bohr attended the Gammelholms School in 1903. He was a good student, but not at the top of his class. In most classes he would finish about third or fourth in classes of about 20 students. Niels, in his final 2 years at Grammelholms, specialized in mathematics and physics<ref>Blaedel, Niels. (1988).Retrieved 30 January, 2009 from,http://histclo.com/bio/b/bohr/bohr-ed.html</ref> . Bohr later enrolled in Copenhagen University under the guidance Professor C. Christiansen, who was a profoundly original and highly endowed physicist.<ref>The Nobel Foundation.(1922).Retrieved on 30 January, 2009 from, http://nobelprize.org/nobel_prizes/physics/laureates/1922/bohr-bio.html</ref>. In 1909, Bohr received his Masters Degree in physics. In 1911, at the age of twenty-five, Bohr also received his PhD in physics at Copenhagen University. CITATION REQUIRED. Neils was 10 when he started school. he went to school with his younger brother harold.<ref>Blaedel, Niels. Harmony and Unity: The Life of Niels Bohr (Science Tech, 1988), 323p.</ref>. In his class many students weared sailer suits in 1901. In his last two years of highschool he specialized in mathmatics and physics. He enjoyed playing soccer with his brother even though his brother was a little better. His class mates knew him because of soccer.<ref>Blaedel, Niels.

While still a student, the announcement by Academy of Sciences in Copenhagen have said a prize to be awarded for the solutions of a certain scientific problem, caused him to take up an experimental and investigation of the surface tension by means of oscillating fluid jets. He conducted his investigation in his father's laboratory carrying out to be received the prized offered, a goal metal from the Royal Danish Academy of Sciences and Letters. <ref>Encyclopedia Britannica.2009.Neils Bohr.encyclopedia Britannica. Jan.23,2009</ref>. In attending Cambridge in England he went under the assistance of J.J Thomson to continue his studies but didn't last long in the Cavendish Laboratory.<ref>Encyclopedia Britannica.2009.Neils Bohr.encyclopedia Britannica. Jan.23,2009</ref>. In the spring of 1912< he went to Manchester to join Professor Rutherford, where he worked on his theoretical work on the absorption on the alpha rays: in 1913 it was published Philosophical Magazine. <ref> J J O'Conner,and E F Robertson.Niels Hendrick David Bohrs.University of Saints Andrews.Jan.23,2009.</ref>. In 1917, Bohr became a professor at Copenhagen University <ref> J J O'Conner,and E F Robertson.Niels Hendrick David Bohrs.University of Saints Andrews.Jan.23,2009.</ref>. In 1920, he was appointed director of the new "Institute of Theoretical Physics." <ref>ScienCentral Inc and The American Institute of Physics 1999.(2003)."NielsBohr1885-1962, Copenhagen,Denmark".Jan.23,2009</ref>. He made many contributions in understanding the structure of properties of the atoms, given him the Noble Prize in 1922 for physics by working on the atomic structure<ref>Msn 1997-2008.Niels Bohr.Man Encarta.

The Bohr Model was proposed in 1915. CITATION REQUIRED During 1913, Niels Bohr, a physicist, managed to explain the spectrum of atomic hydrogen with the help of Rutherford’s description of the atom. <ref> Fendt, W. “Bohr's Theory of the Hydrogen Atom” May 30, 1999. February 5, 2009, from http://www.walter-fendt.de/ph11e/bohrh.htm</ref> The key constituent of the Bohr atomic model is the energy of the electrons are restricted to certain discrete values; that is, the energy is quantized. This means that only certain orbits with certain radii are allowed; orbits in between simply don't exist. CITATION REQUIRED
Bohr studies soon became more and more theoretical and his doctor’s disputation began to be the work on the explanation of the properties of the metals with the aid of the electron theory. Later, he continued with more studies but on the structure of atoms on the basis of Rutherford’s discovering of the atomic nucleus. Bohr also contributes to the clarification of the problems encounter in quantum physics, in particular by developing the concept of complementary. <ref> J J O’Conner, and E F Robertson. Niels Hendrik David Bohrs. University of Saint Andrews. Jan. 23,2009. </ref>. By introducing conceptions borrowed from the Quantum Theory as established by Plank, he succeeded in working out and presenting a picture of atomic structure that, with improvement that are still used today. By the time he was twenty-seven, Bohr constructed a model of the hydrogen atom with quantized energy levels that agreed with the hydrogen emission results. <ref> Msn 1997-2008. Niels Bohr. Msn Encarta. Jan. 23,2009. </ref>. Niels Bohr is a central figure in the drive to understand the atom. He later got involved in World War II with the Atomic Energy Project devoting his work to the peaceful atomic weapons.<ref> The Columbia Encyclopedia, Sixth Edition(2008). “Niels Hendrik David Bohr”.

Years later, Bohr died on November 18, 1962 in Copenhagen.<ref> The Columbia Encyclopedia, Sixth Edition(2008). “Niels Hendricks David Bohr”. Jan 23, 2009. </ref> During Bohr’s lifetime, he made many discoveries and won prizes for his hard work. He also got to work with other professors who made a difference in chemistry. Even though his model of the hydrogen atom was proven incorrect, to this day it is still used because it helps explain that particular atom. <ref> Erin Pfeifer, Niels Bohr-Danish- Physicist- 1885-1962. Jan. 23, 2009</ref>. As a result of Bohr’s self drive, he put a lot of his time and effort into learning more and more about physics <ref> Erin Pfeifer, Niels Bohr-Danish- Physicist- 1885-1962.
