Review of Unit 3- Energy and Bonding (Chapter 10: Energy (10.1 Energy,…

- - - - Principal energy level 2 has two sublevels. These sublevels are labeled 2s and 2p. The 2s sublevel consists of one orbital (called the 2s), and the 2p sublevel consists of three orbitals (called 2px, 2py, and 2pz).
      - For example, level 3 has three sublevels, which we label 3s, 3p, and 3d. The 3s sublevel contains a single 3s orbital, a spherical orbital larger than 1s and 2s. Sublevel 3p contains three orbitals: 3px, 3py, and 3pz, which are shaped like the 2p orbitals except that they are larger. The 3d sublevel contains five 3d orbitals with the shapes and labels shown in the Textbook.
      - Level 4 has four sublevels labeled 4s, 4p, 4d, and 4f. The 4s sublevel has a single 4s orbital. The 4p sublevel contains three orbitals (4px, 4py, and 4pz). The 4d sublevel has five 4d orbitals. The 4f sublevel has seven 4f orbitals.
        The 4s, 4p, and 4d orbitals have the same shapes as the earlier s, p, and d orbitals, respectively, but are larger. We will not be concerned here with the shapes of the f orbitals.
