Orbital gives the orientation of electrons in a set of orbitals.

Electronic Structure: Orbitals

Concept #1: Relationship between subshell and orbital shape

Example #1: Based on the following atomic orbital shape, which of the following set of values is correct.

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

Concept #2: Set of Orbitals

Example #2: Provide the identity of a set of orbitals that exist in the 4th energy level and p sublevel.

Concept #3: Sets of Orbitals

Practice: Which of the following statements is false?

a) A set of d orbitals contains 5 orbitals.
