Starter Write the formulae for the following: a) Oxygenb) Methane c) Chlorined) Calcium chloride e) Neonf) Lithium oxide
Aim of lesson: To investigate the conductivity of different elements.
Conduction of Elements Aim: To investigate which elements conduct electricity.
Method Wires 3v DC Bulb Electrodes Beaker containing compound
Results: Element Metal/ Non-metal Conductor/ insulator Copper foil Iron Sulphur Magnesium Silicon Oxygen Aluminium Tin Lead Iodine Carbon(graphite)
Conclusion: All metals conduct Non-metals do not conduct (except carbon in the form of graphite)
Metals Found on the LHS of the Periodic Table. Metals conduct when they are solid or liquid.
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.
Starter 1. What type of bonding is present in metals? 2. In what state do metals conduct? 3. What type of elements are present in covalent compounds? 4.
Starter 1. What is electricity? 2. Write the formula for Calcium chloride 3. What type of bonding is present in the following: a) Phosphorous chloride.
Starter 1. Explain why molten sodium chloride conducts electricity but solid sodium chloride does not. 2. Explain why although neither lithium chloride.
BONDING, STRUCTURES & PROPERTIES CONDUCTIVITY. After completing this topic you should be able to : BONDING, STRUCTURE & PROPERTIES CONDUCTIVITY Write.

Elements, mixtures and compounds. Elements Made up of only one kind of atom.
Atoms and Elements. Atoms Atoms are the “building blocks” of all matter and are the simplest form of molecule. They are all made up of protons, neutrons.
Starter Copy and complete the following: 1. Electricity is a _____ of ________. 2. Metals _______ electrons to from _______ ions. 3. Non-metals _____ electrons.
Subatomic particleRelative chargeRelative mass Proton Neutron Electron Define: mass number:…………………………………… …………………………………………………………. Proton number:…………………………………
The empirical formula of a compound is the simplest ratio of the different atoms in it. For example, for ethane (C 2 H 6 )it is CH 3. You can work out.
Electricity in Chemistry An electric current is a flow of charge – this can be either electrons or charged particles called “ions” A conductor is a substance.
Starter Questions. State the page of your data book which shows: 1)The melting and boiling points of elements 2)The melting and boiling points of compounds.
S2 Science Elements and Compounds REVISION By contributing to investigations into familiar changes in substances to produce other substances, I can describe.
