  1. More on Electron Configurations

  2. Identify the blocks on your periodic table. Each block is named after its characteristic orbital; thus, the blocks are: He is in the S Block. Shell number minus 1. Shell number minus 2.

  3. 2. Write the electron and orbital diagram for Z = 20.

  4. 2. Write the electron configuration and orbital diagram for Z = 20 Ca. Valence Electrons (Lewis Dot Structure) – are all e’ in the outermost e’ shell (in the shell with the highest shell number. Ca
