P ATTERNS IN THE P ERIODIC T ABLE 1) Are the elements arranged in order of increasing atomic number or atomic weight (mass number) ? They are in order by atomic number. In the 5 th period of the PToE:

P ATTERNS IN THE P ERIODIC T ABLE What is the same about each period (row)? Same highest energy level Ex) Row 2 all have 2 s, 2 p

P ATTERNS IN THE P ERIODIC T ABLE What is the same about each group (column)? Same highest orbital Ex) Column 13 all end in p 1

P ATTERNS IN THE P ERIODIC T ABLE What is the same about each group (column)? Same dots in Lewis Dot Diagram Same number of valence electrons

P ATTERNS IN THE P ERIODIC T ABLE Vocabulary: Period – a horizontal row of elements in the PToE - they have the same highest energy level Group – a vertical column of elements in the PToE For the s- and p-blocks, they have the same: - end electron configuration - number of valence electrons - dots in Lewis dot diagram - chemical properties
