  • Overview

    Overview
    Niels Henrik David Bohr (October 7,1885 - November 17,1962) was a famous Danish Physicist born in Copenhagen, Denmark. He is well known as one of the most famous physicists of the 20th century for his work regarding physics including atomic and molecular structure.

  • Early Years

    Early Years
    Bohr enrolled at the University of Copenhagen to pursue a degree in physics in 1903. Nearly a decade later in 1911 he received his doctorate in the field.

  • Bohr's Atomic Model

    Bohr's Atomic Model
    Bohr was most famously known for his model of the atom. Based largely off of Ernest Rutherford's model, Bohr speculated that electrons surrounding the nucleus orbit in specific distances from the atoms center.

  • Bohr's Atomic Model-2

    Bohr's Atomic Model-2
    After suggesting electrons have certain distances from the nucleus at which they orbit Bohr theorized that these electrons are able to "jump" into different orbits both within the atom and externally.

  • Bohr's Atomic Model-3

    Bohr's Atomic Model-3
    Niels Bohr observed that when these electrons made "jumps" between orbits it would result in electromagnetic radiation being absorbed or emitted. Absorption resulted in the electron jumping to a higher orbit, and emission resulting in a lower orbit. Lower in this case meaning closer to the atoms nucleus.

  • Nobel Prize

    Nobel Prize
    Although his model was not accepted widely across the scientific community right away it later gained ground and due to his studies in the molecular structure of an atom Niels Bohr went on to receive the Nobel Prize in Physics in 1922.

  • Significant Achievements

    Significant Achievements
    Niels Bohr was given many awards for his significant accomplishments within physics. Some of his significant achievements include:
    -Hughes Medal (1921) for Theoretical Physics Research
    -Nobel Prize (1922) for Atomic Structure and Quantum Physics
    -Matteucci Medal (1923) for Fundamental contributions to Physics
    -Franklin Medal (1926) for Physics
    -Max Planck Medal (1930) for his contributions to Quantum Theory
    -Copley Medal (1938) for Outstanding achievements in scientific research
