Niels+Bohr+Hall


 * __Niels Bohr__**

**Where did his research take place? ** Bohr attended Copenhagen University in Denmark for eight years and received a doctorate degree. He also worked at Cavendish Laboratory at Cambridge, but it wasn’t until he went Manchester in 1913 when he took over the Rutherford’s atom theory and refined it. He began to build an atomic model that helped him demonstrate his atomic theory. ** What type of equipment was used to develop this theory? ** Bohr's theory and construction of the atomic structure was developed by the incorporation of information fron Rutherford's ideas of the atom and Planck's Quantum Theory.



** Bohr’s experiment for his atomic theory had four principles: ** "1. Electrons assume only certain orbits around the nucleus called “stationary” orbits 2. Each orbit consists of energy with connected with it. 3. Light is emitted when an electron jumps from a higher to a lower orbit and absorbed when it goes from lower to higher orbit 4. The energy and frequency of light emitted or absorbed is given by the different between the two orbit energies"

**What did he do? ** Bohr improved upon the research of Thomas and Rutherford who made the nuclear model. 1. He proposed that electrons moved restrictedly in protective shells. 2. He also stated that electrons can have high and low energy levels. The result is light is emitted by an atom.


 * Bohr's atomic model... **

Did his theory have any errors? ** 1. Bohr specially predicted the energy level and location of the electrons, but only an approximate location can be predicted no one can truly be right.

**Did you know: ** Bohr had to escape the Nazis in 1943; he had to be taken to Sweden by a fishing boat!
