  • To succeed with this topic you need to: 
    • be able to find an atom/element in the Periodic Table and decide which group it is in 
    • know that the number of the group an element is in tells you how many electrons it has in its outer shell 
    • understand how to draw dot-and-cross diagrams to show covalent bonding 
    • understand that positive ions have lost electrons, and negative ions have gained them, and that the size of the charge on the ion tells 
    you how many electrons are involved
