      3.1 The Periodic Table Understandings: • The Periodic Table is arranged into four blocks associated with the four sub-levels: s, p, d, and f. • The Periodic Table consists of groups (vertical columns) and periods (horizontal rows). Guidance The group numbering scheme from group 7 to group 78, as recommended by IUPAC, should be used.
