Periodic Table of the Elements

Main Group

The main group elements of the periodic table are those elements that belong to the "s" and "p" blocks. Counting the columns or table groups across the table ignoring the transition elements gives 8 element groups which match the filling of the eight spaces for electrons in the ns and np subshells, ns2np6. The "s" subshell can hold two electrons while the "p" subshell can hold six electrons for a total of eight. One good aspect about the 1A to 8A group numbering system is that the group number indicates the number of valence ( outer ) electrons for atoms in the main group elements.
