Starter Write the formulae for the following: a) Oxygenb) Methane c) Chlorined) Calcium chloride e) Neonf) Lithium oxide
3
Aim of lesson: To investigate the conductivity of different elements.
4
Conduction of Elements Aim: To investigate which elements conduct electricity.
5
Method Wires 3v DC Bulb Electrodes Beaker containing compound
6
Results: Element Metal/ Non-metal Conductor/ insulator Copper foil Iron Sulphur Magnesium Silicon Oxygen Aluminium Tin Lead Iodine Carbon(graphite)
7
Conclusion: All metals conduct Non-metals do not conduct (except carbon in the form of graphite)
8
Metals Found on the LHS of the Periodic Table. Metals conduct when they are solid or liquid.
9
Metallic bonding Exists between metal elements only. Metals conduct due to the ‘sea of delocalised electrons’ which move around the outside of the atoms and so carry the current.
