Bohr and The Hydrogen Atom

Physicist Niels Bohr used the hydrogen atom to explain why electrons are not located in the nucleus attached to protons. After all, opposites attract - the negative electron and the positive proton should be attracted to one another and connected. Bohr discovered that electrons are located outside of the nucleus on energy levels. In this topic, you will investigate the findings of Niels Bohr, and you will analyze the Bohr models of specific elements, looking at the key relationships that exist.

Essential Questions

• Where are the electrons located in an atom, and how does the location determine the energy of the electron?
• What are Bohr models, and how are they analyzed?
