#C4.3.1
explain how the bulk properties of materials (including strength, melting point, electrical and thermal conductivity, 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 covalent bonds
#C4.3.3
explain that the vast array of natural and synthetic organic compounds occurs due to the ability of carbon to form families of similar compounds, chains and rings
#C4.3.4
describe the nature and arrangement of chemical bonds in polymers with reference to their properties including strength, flexibility or stiffness, hardness and melting point of the solid
#C4.3.5
describe the nature and arrangement of chemical bonds in giant covalent structures
#C4.3.6
explain the properties of diamond and graphite in terms of their structures and bonding, include melting point, hardness and (for graphite) conductivity and lubricating action
#C4.3.7
represent three dimensional shapes in two dimensions and vice versa when looking at chemical structures e.g. allotropes of carbon
#C4.3.8
describe and compare the nature and arrangement of chemical bonds in ionic compounds, simple molecules, giant covalent structures, polymers and metals
