C2 - properties of ionic, covalent and metallic structures

Properties of ionic compouds

giant - millions of ions are strongly bonded, very high melting and boiling points, dissolve in water, conducts electricity ONLY IN LIQUID FORM

Properties of simple covalent molecules

weak intermolecular forces - easy to break apart from eachother, low melting points, do NOT conduct electricity

Properties of polymers

long chain of small molecules joined together, weak intermolecular forces, higher melting points, as more energy needed to break apart

Properties of giant covalent structures

e.g diamond, graphite, very high melting points, high boiling points

Properties of metal and alloys

giant structures, strong metallic bonds, high melting and boiling points, malleable and ductile, good conductors of heat and electrcity
