Explain why ionic compounds are soluable in water.
Explain why ionic compounds conduct electricity in molten and aqueous state but not in solid state.
Describe or draw the structure of NaCl lattice.
Explain why ionic compounds are brittle.
Explain why ionic compounds possess high melting temperatures (points)
Explain why ionic aqueous solutions undergo electrolysis.
Suggest ways in which ionic compounds differ from metallic and coavalent compounds. Explain your answers.
Draw dot and cross symbols for simple coavalent compounds.
Explain why simple covalent substances possess low melting points, are insoluble in water, do not conduct electricity, etc.
Draw the structures of diamond and graphite.
explain why diamond and graphite have high sublimation points (melting points).
Explain why only graphite conducts electricity and not diamond.
Explain why diamond is hard.
By referring to the structure and properties of diamond and graphite explain some of their uses.
Describe how metals form metallic bonding.
Explain why metals conduct electricity and heat, are malleable and ductile using their structures.
What is a covalent bond
That's pretty much what you can get !
Remember when explaining why substances conduct electricity refer to free mobile electrons which can move through the structure not just free electrons
