Chapter 5. Electrons in Atoms. The Bohr Model. An electron is found only in specific circular paths, or orbits, around the nucleus. Each orbit has a fixed energy. The orbits are called ‘energy levels.’. Energy Levels. Energy levels are like the rungs of a ladder:
Electrons in Atoms
n = 1, 2, 3, 4 …
are dumbbell- shaped
4 out of the 5 d orbitals have clover leaf shapes
are more complicated
The number and kinds of atomic orbitals depend on the energy sub level.
The maximum number of electrons that can occupy a principle energy level is 2n2.
