G. Abbreviated Electron Configurations

III. Electron Configuration and the Periodic Table. A. Blocks of the Periodic Table. 1. Notice that all elements in the same group have configs that end similarly. For example group 1A all end in Xs1. Group 4A all end in Xs2 Xp2. We use this information to break the table down into blocks. 2. Groups 1A and 2A are the s block. 3A-8A are the p block. ................
