__** Transition Metals: **__

Check [|this] out for an intro video to the properties of Transition Metals from GCSE Bitesize.

[|Transition Metal Notes] //Reading://

For further information at a slightly deeper level have a read of: [|Colour and Transition Metals]

Have a go at the cloze activity which will also give you notes on Transition Metal properties and chemistry [|here]

Try this [|Transition metal quiz] - you will need to remember your precipitation and colours, or else refer to your year 12 notes..

__** Halogens and their Halides: **__ read through [|**this page**]

__** Periodic Trends: **__ 3 column table for Radii, Ionisation Energy and Electronegativity: Graphing of Atomic Radii and Ionisation Energy: Practice using

__** Polarity of Bonds and Molecules: **__ __[|Polar and Nonpolar bonds interactive]__ - this page also has links to further interactive tutorials etc. Good for learning definitions and a refresher..

Have a go at this [|cloze] activity to help you build on your notes, understanding and practice of different types of bonding - particularly dipoles and hydrogen bonding.

__** Enthalpy: **__ Endothermic and Exothermic

__** Enthalpy Changes **__ Read p28-32 of notes manual, answer these Qs and highlight the **key** parts of text where you found your answers.

[|Bond Enthalpy Breakdown] Links to a page that breaks down calculating enthalpy for a reaction through bond enthalpies. Worked examples.

__** Extra questions and guidance for unit standards: **__ Further practise in textbook. Go over: Periodic trends: electronegativity, oxidising ability, atomic radii, nuclear charge, ionisation energy Halogens and their halides (e.g. Br and HBr): boiling point trends, oxidisng ability Transition metals: Common oxidation states and colours, and reason for both. Enthalpy: Calculating enthalpy for reactions, using enthalpy of formation and combustion. Calculating enthalpy using bond enthalpies.
