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
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
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
explain how the reactions of elements are related to the arrangement of electrons in their atoms and hence to their atomic number
explain how the atomic structure of metals and non-metals relates to their position in the Periodic Table
describe the nature and arrangement of chemical bonds in ionic compounds
explain ionic bonding in terms of electrostatic forces and transfer of electrons
calculate numbers of protons, neutrons and electrons in atoms and ions, given atomic number and mass number or by using the Periodic Table
construct dot and cross diagrams for simple ionic substances
explain how the bulk properties of ionic materials are related to the type of bonds they contain
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
describe the limitations of particular representations and models of ions and ionically bonded compounds, including dot and cross diagrams, and 3-D representations
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
