C4.3 How do bonding and structure affect the properties of materials? C4.3.1 explain how the bulk properties of C2 Structure, bonding 58 Also C7 Page materials (including strength, melting and the properties of 254 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 C2 Structure, bonding 76-84 covalent bonds and the properties of matter C4.3.3 explain that the vast array of C2 Structure, bonding 76-84 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 Structure, bonding 74 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 Structure, bonding 76 arrangement of chemical bonds in giant and the properties of covalent structures matter C4.3.6 explain the properties of diamond C2 Structure, bonding 77 Diamond pg 80, and graphite in terms of their structures and the properties of Graphite pg 82, and bonding, include melting point, matter hardness and (for graphite) conductivity pg 84 and lubricating action C4.3.7 represent three dimensional C2 Structure, bonding 90 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 Structure, bonding 56-64 and arrangement of chemical bonds in and the properties of ionic compounds, simple molecules, giant matter covalent structures, polymers and metals C4.4 Why are nanoparticles so useful? C4.4.1 compare dimensions to C2 Structure, bonding 86 ‘nano’ typical dimensions of atoms and and the properties of molecules matter C4.4.2 describe the surface area to C2 Structure, bonding 87 volume relationship for different-sized and the properties of particles and describe how this affects matter properties
