Practice: How many different values of m_{l} are possible for a 4d set of orbitals?

The **Magnetic Quantum Number** gives the location of an electron within a specific orbital.

Concept #1: Magnetic Quantum Number

Example #1: Provide the identity of a set of orbitals that exist in the 4th principal level and f sublevel

Concept #2: The Magnetic Quantum Number (*m*_{l})

Example #2: Which of the following is not a valid magnetic quantum number for the 7f set of orbitals?

Practice: How many different values of m_{l} are possible for a 4d set of orbitals?

Practice: Select a correct set of values for an electron found within the designated 5f orbital.

Practice: Which of the following statements is false?

a) A set of *d* orbitals contains 5 orbitals.

b) A set of 4s orbitals would have more energy than a set of 3p orbitals.

c) The second shell of an atom possesses *d* orbitals.

d) A set of *f* orbitals contains 3 orbitals.

e) The first energy level contains only *s* orbitals.
