Bohr's Discoveries

  • Bohr's discoveries started in 1912 after working with Ernest Rutherford on his gold foil experiment. 
  • The gold foil experiment proved the existence of an atom's nucleus.

Bohr's Discoveries

  • Using this new found knowledge and the idea of Quantum Theory, Bohr created an accurate picture of an atom's structure.

Bohr's Discoveries

  • In 1936, Bohr discussed the movement and orbit of electrons around the nucleus and between the energy levels in an atom.

Bohr's Discoveries

  • Bohr stated that electrons move in set orbits (energy levels) around the nucleus, they can move into different energy levels by gaining or losing energy but cannot be in-between energy levels.

Bohr's Discoveries

  • This work in atomic structure led Bohr to a Nobel Prize in physics in 1922.

The Bohr Atom

Bohr's Impact

  • Bohr's discoveries impacted the world's understanding on the atom.
  • It allowed scientists to have a clear understanding of the exact composition and structure of atoms, and improved their understandings of the laws atoms are bound to.
