#C2.3.1
recall the simple properties of Group 0 including their low melting and boiling points, their state at room temperature and pressure and their lack of chemical reactivity
#C2.3.2
explain how observed simple properties of Groups 1, 7 and 0 depend on the outer shell of electrons of the atoms and predict properties from given trends down the groups
#C2.3.3
explain how the reactions of elements are related to the arrangement of electrons in their atoms and hence to their atomic number
#C2.3.4
explain how the atomic structure of metals and non-metals relates to their position in the Periodic Table
#C2.3.5
describe the nature and arrangement of chemical bonds in ionic compounds
#C2.3.6
explain ionic bonding in terms of electrostatic forces and transfer of electrons
#C2.3.7
calculate numbers of protons, neutrons and electrons in atoms and ions, given atomic number and mass number or by using the Periodic Table
#C2.3.8
construct dot and cross diagrams for simple ionic substances
#C2.3.9
explain how the bulk properties of ionic materials are related to the type of bonds they contain
#C2.3.10
use ideas about energy transfers and the relative strength of attraction between ions to explain the melting points of ionic compounds compared to substances with other types of bonding
#C2.3.11
describe the limitations of particular representations and models of ions and ionically bonded compounds, including dot and cross diagrams, and 3-D representations
#C2.3.12
translate information between diagrammatic and numerical forms and represent three dimensional shapes in two dimensions and vice versa when looking at chemical structures for ionic compounds
