D-orbital

Definition

The d-orbital is a type of atomic orbital that is found in the electron shells of atoms. It is characterized by a more complex shape and higher energy level compared to the s-orbital and p-orbital, and plays a crucial role in the electronic structure and bonding of certain elements, particularly transition metals.

Review Questions

• Explain the key features of the d-orbital and how it differs from the s-orbital and p-orbital.
  • The d-orbital is a type of atomic orbital that is characterized by a more complex shape with five lobes arranged in a specific spatial pattern. Unlike the s-orbital, which has a spherical shape, and the p-orbital, which has a dumbbell-like shape, the d-orbital has a more intricate geometry. Additionally, the d-orbital has a higher energy level compared to the s-orbital and p-orbital, allowing it to hold up to 10 electrons. This higher energy and unique shape of the d-orbital contribute to the diverse chemical and physical properties of transition metals, which have partially filled d-orbitals in their electron configuration.
