- Niels bohr1. Believed electrons occupy specific, or exact, energy levels2. Said energy levels are specific distances from the nucleus3. Said there are specific amounts of energy that are requiredto move electrons to the next energy level
- Erwin Schrodinger1. Modeled a wave equation that allowed scientists to identify property of electrons as both a wave and a particle 2. Believed electrons do not stay in a certain orbit but can have a predicted zone around the nucleus 3. Believed the wave equation could predict the probable (but not exact) location of an electron
