Arrangement of elements
What this topic asks you to be able to do
- outline the layout of the Periodic Table, with elements placed in periods and groups and ordered by increasing proton number/atomic number
- outline the shift from metallic towards non-metallic character as one moves across a period
- outline how the group number of an element connects with the charge carried by the ions that element forms
- account for why elements within one group of the Periodic Table resemble each other chemically, by reference to their electronic configuration
- explain how knowing where an element sits in the Periodic Table lets us forecast its properties
