Describe the azimuthal quantum number (l) and its relationship to the shape of the orbital.

• The azimuthal quantum number (l) determines the energy level of the orbital.

• The azimuthal quantum number (l) determines the shape of the orbital.

What is the Pauli exclusion principle and how does it relate to the quantum numbers of electrons in an atom?

• The Pauli exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers.
