The Angular Momentum Quantum Number gives the shape of the atomic orbitals.

Angular Momentum Quantum Number

Concept #1: Relationship between n and l

Example #1: What are all possible values for when n = 4?

Concept #2: Relationship between l and subshell

Example #2: What are the possible values for n and l for an electron found in the 3rd principal level and d sublevel?

Practice: Provide all the possible values of l for a 2 energy level.

Practice: How many sublevels are contained in the third shell (n = 3) for a given atom?

Concept #3: Relationship between subshell and orbital shape

Example #3: Based on the following atomic orbital shape, which of the following set of quantum numbers is correct.

Practice: Which of the following orbitals possesses the most orbital shapes?
