Niels Henrik David Bohr (1885-1962) Danish physicist who is considered as the greatest physicist of all time, inventor of the Atomic Theory Bohr, inventor of the liquid drop model to atomic models, expert physicists are commensurate with Einstein, recipient of Nobel Prize in physics. Bohr was not the first in the world to discover the structure of atoms or atomic model.
Atomic structure was discovered by Rutherford, English physicist, in 1911. But Rutherford atomic structure (atomic structure by observing Rutherford) is less clear. According Rutherford atom consists of a core surrounded by planets. But Rutherford cannot explain how far the distance from the core electrons. Bohr atom model Rutherford repair.
Bohr was the first person in the world to apply quantum theory to solve problems of atomic structure. He gave an important contribution to the development of quantum physics for over 50 years.
Bohr was born Copenhagen, Denmark, on October 7, 1885 and died in Copenhagen are also on the date of 18 November 1962 at the age of 77 years. His father was Christian Bohr; professor of physiology at the University of Copenhagen, His mother was Ellen Adler Bohr and includes illustrious family in Denmark. Since childhood, Bohr was visible as a bright child, who loves to read and study scientific books.
In 22 years, while still a senior at the University of Copenhagen, Bohr received the gold medal of the Copenhagen science institution for his work on the water surface. At the age of 26 years he earned a Doctor for his thesis on electron metal. Then he went to England to study the atom together with Thomson, inventor of the electron. After that he went to Manchester to study the atomic structure with Rutherford. He received the Nobel Prize in 1922 at age 37, to physics because their atomic theory.
Bohr is a great teacher, doctor, director of the Institute of Physics Theory, and author. Bohr authored a book on atomic theory. The book was published in 1913. He uses beams of light Planck’s theory and model of the atom Rutherford to explain the light that comes on the hydrogen atom. According to Bohr, the electrons surrounding the nucleus in specific orbits. In the outer orbit and there are atoms in orbit. Orbit within the orbit of an electron orbit near the outer core can accommodate more electrons. Electrons in outer orbits determine the chemical properties of atoms. Sometimes the electron in outer orbit to orbit the jump. At the time an electron jumps that give off light. Book by Bohr those others such as: Spectrum and Structure of Atomic Theory (1922), Atomic Theory and the Description of Nature (1934), Atomic Physics and Human Knowledge (1958).
Bohr married Margrethe Norlund in 1912. Apparently not the wrong choice. His wife is a suitable companion for him. From that marriage they were blessed with 6 people ank men, but two people died. Which four people managed to be respected and there is even one who gets the position, such as Bohr, Bohr as a director is to replace the institute. Bohr bener aware of the dangers and benefits of the atom for the people of amusia. He experienced World War II and how the Hiroshima and Nagasaki destroyed by atom bombs. In 1950 he proposed to the UN to run the open-world wisdom to avoid war. The statesman should exchange information freely, until countries can and want to mutual trust and show that despite a prominent physicist, Bohr’s noble spirit and thinking about the welfare of mankind.
