hope we have a hard exam
makes it fun

EDIT: I didn't make this. but this is very useful! (HappyHylian Cheers!)
Possible C4 Six Markers
Describing Group 1 (Alkali metals).
Describing Group 7 (Halogens)
Comparing Group 1 and Group 7 (perhaps in less detail).
Getting data and explaining it with knowledge of Group 1 and Group 7.
The history of the periodic table (given a table with Mendeleve's ideas and told to say why it works/why it doesn't, etc).
Explaining line spectrums/how used/useful.
Describing laboratory safety, different hazard symbols, how to work safely with dangerous chemicals, examples of dangerous chemicals and why they're dangerous. (Alkali metals and halogens).
Describing ionic bonding in detail.
The makeup of the atom, different rules it follows (N of ptotons = N of electrons). Electrons = negative, tiny, no mass, etc. Basically just a describe question.
Generally comparing the structure of 2 given atoms.
Possible C5 Six Markers
Describing and explain molecular substances and their properties. (Possibly interpreting data).
Explaining covalent bonding.
Identifying negative ions. (some kind of "Class 11GL did an experiment and they got these results, explain them".
Comparing Diamond and GraphiteOR comparing diamond and silicon dioxide OR comparing silicion dioxide and graphite. Properties, structure, characteristics, etc.
Describing and explaining electrolysis in detail.
Describing and explaining metal's properties. Why useful, etc.
Explaining the environmental impact of chemistry. Probably given a scenario. "Paul is against the building of a mine, discuss the advantages and disadvantages of a mine".
Comparing hydro/litho/atmosphere.
Identifying positive ions using data from a table.
Possible C6 Six Markers
Describing what the chemical industry does.
Describing the 7 stages of chemical synthesis. (Choosing the reaction, risk assessment, calcuating quantities of reactants, choosing the apparatus and conditions, isolating the product, purification, measuring yield and purity).
Describing purification and measuring yield in detail. (filtration, evaporation and crystallisation and drying, percentage yield = actual yield / theoretical yield x 100).
Describing how to do a titration. Example, "John wants to take an accurate titration, describe and explain how he does this".
Comparing exothermic and endothermic reactions. Very likely to come alongside a graph.
Describing and explaining rate of reaction, possibly how industry uses it to their advantage.
Describe/explain collision theory.
Describe how to measure speed of a reaction in 3 different ways. (precipiation and colour change, change in mass and volume of gas given off).
Describing acids reacting with different metals. Possibily explaining data.

Bold includes ones that have come up before (apart from the 2014 ones and the old dual award style - I'll add them soon to this list)
