(d) The Periodic Table
1.18 understand how elements are arranged in the Periodic Table:

  • in order of atomic number
  • in groups and periods
1.19 understand how to deduce the electronic configurations of the first 20 elements from their positions in the Periodic Table
1.20 understand how to use electrical conductivity and the acid-base character of oxides to classify elements as metals or non-metals
1.21 identify an element as a metal or a non-metal according to its position in the Periodic Table
1.22 understand how the electronic configuration of a main group element is related to its position in the Periodic Table
1.23 understand why elements in the same group of the Periodic Table have similar chemical properties
1.24 understand why the noble gases (Group 0) do not readily react
