Atomic Structure
In 1913, Niels Bohr studied the structure of atoms based on Rutherford’s discovery of the atomic nucleus, and successfully devised a demonstration of a picture of the atomic structure. With the help of later improvements, his discovery still stands as a clear explanation of the chemical and physical properties of the elements. -
Discovery of Hafnium
Bohr predicted that the undiscovered atomic element 72 would resemble zirconium. This correct prediction led to the discovery of Hafnium in 1923 which was named after the Latin translation of Bohr’s hometown of Copenhagen. Although it’s existence was predicted by Bohr, this element was actually discovered by Dirk Coster, a danish chemist, and Hungarian chemist George Charles de Hevesy. -
Principle of Complementarity
In 1927, Bohr created the principle of complementarity. This theory states that a physical phenomenon on an atomic level is presented differently depending on the experimental setup used to observe it. Light can be seen as waves or as particles but not at the same time for example. https://youtu.be/EUdBxngtw1o -
Compound Nucleus Model
Bohr partnered with American Physicist John Wheeler in 1939 to develop the liquid drop model. This model explained nuclear fission theoretically by showing the structure of the nucleus as a drop of liquid. It explained the process of fission by illustrating two new drops forming from one. -
