C4.3 How do bonding and structure affect the properties of materials? C4.3.1 explain how the bulk properties of C2 Bonding, Structure 39 materials (including strength, melting and the properties of point, electrical and thermal conductivity, matter brittleness, flexibility, hardness and ease of reshaping) are related to the different types of bonds they contain, their bond strengths in relation to intermolecular forces and the ways in which their bonds are arranged, recognising that the atoms themselves do not have these properties C4.3.2 recall that carbon can form four Not explicit covalent bonds C4.3.3 explain that the vast array of C2 Bonding, Structure 54 natural and synthetic organic compounds and the properties of occurs due to the ability of carbon to form matter families of similar compounds, chains and rings C4.3.4 describe the nature and C2 Bonding, Structure 43 arrangement of chemical bonds in and the properties of polymers with reference to their properties matter including strength, flexibility or stiffness, hardness and melting point of the solid C4.3.5 describe the nature and C2 Bonding, Structure 44 arrangement of chemical bonds in giant and the properties of covalent structures matter C4.3.6 explain the properties of diamond C2 Bonding, Structure 54-55 and graphite in terms of their structures and the properties of and bonding, include melting point, matter hardness and (for graphite) conductivity and lubricating action C4.3.7 represent three dimensional C2 Bonding, Structure 54-55 shapes in two dimensions and vice versa and the properties of when looking at chemical structures e.g. matter allotropes of carbon C4.3.8 describe and compare the nature C2 Bonding, Structure 33-46 Not direct and arrangement of chemical bonds in and the properties of comparison but ionic compounds, simple molecules, giant matter all the covalent structures, polymers and metals information is given to allow comparison
