It depends oer you are GCSE or A level. Also, remember to distinguish between bonding and structure (it looks from your post that you have confused them).
B O N D I N G
IONIC Transfer of one or more electrons from a metal to a non-metal species. Aim for full (empty) outside shells.
COVALENT Shared pair of electrons between the atoms. Again aim for full outer shells (counting the shared electrons too).
DATIVE COVALENT As covalent except that both electrons of the pair come form one of the atoms.
METALLIC Close packed metal atoms have overlapping outside shells. The electron(s) in these outer shells are able to travel around the whole of the metal. This is a delocalised sea of electrons.
S T R U C T U R E
IONIC LATTICE Ionic bonding between ions. Giant lattice with the positive ions arranged so that they are as near as possible to negative ions and as far as possible from other positive ions. NaCl is a good example.
COVALENT MOLECULES Small groups of atoms joined by covalent bonds. Each molecule is held to its neighbours by relatively weak intermolecular forces. Hence low mp and bp.
COVALENT GIANT LATTICE / MACROMOLECULE All the atoms of the structure are held together by covalent bonds. A good example is diamond.
METALLIC LATTICE All the atoms are arranged in a lattice with the delocalised sea of electrons all around them.
Structures explain the overall physical properies of the substance (eg mp / bp / conduction etc) Bonding deals with the linking of one atom to another.
Happy to help. The exact details of which bits of information you need will be in your sepcification. If you don't have one, they are available from the Board's website. Let me know if you have difficulty.

Hope this helps.
Thanks for this nice post. Will you tell me about carbon bond, what type bond its use in about 100 degree temperature?
Hi, can someone help me to remember the different types of bonding?
1) Covalent
2) Giant Covalent
3) Metallic
4) Ionic
5) and is there one more . . .?
Thanks guys!!
:D

Thanks for the concise facts! I see what you mean about the bonding ans structure, my mistake! Thanks alot once more,

I can't really tell from your question what you are asking.
The carbon - carbon covalent bond is very strong.
Diamonds are formed from carbon atoms joined by covalent bonds. They form tetrahedral structures which make the diamond very hard.
Graphite is much softer and has covalent bonds between most of the carbon atoms (in layers of hexagons) but has weaker bonds between the layers.
Re-post and I will try to answer your question in more detail.
