(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 |
