How the bloody hell am I supposed to know whether to talk about bonds (metallic, ionic etc) or IMF's?! I would mention both however the god damn mark scheme says mentioning the wrong one counts as a chemical error :cry:

Do you have molecules in metal?

Do you have molecules in ionic crystal?

Bonds and IMF are completely different.

Bonds are between atoms. EG: Water has 2 bonds. Both are from the O atom to the H atoms.
Intermolecular forces exist between molecules. This means WATER molecules have attractions between one another. (NOTE: WATER! Not atoms! The molecule as a whole is attracted).

Remember: INTERmolecular. BETWEEN molecules.
Bonds: Between atoms.

InterMOLECULAR forces do not exist in metallic or ionic bonded structures. Why? Because they are not MOLECULES. Remember: Molecules involve covalent bonds

Sorry for the caps. Just trying to empathize to help you

So, where does the hydrogen bond fits into this scheme? It bonds molecules, yet it is located on atoms.

Metallic bonding is only when you talk for metals
Ionic bonding takes place between a metal and non-metal.
Covalent bonding takes place between two non-metals

Ionic bonding takes place between a metal and non-metal.
Especially in caesium auride
