chemistry AQA paper 1

I'm predicting LOTS of maths!
And:
Potentially not the history of atom/periodic table as that has come up SO much

- Standard atomic structure etc questions
- Groups of the periodic table and their reactions eg why does group 7 get less reactive going down the group
- Bonding will always come up
- Properties of giant ionic/covalent structures
- Properties of metals and alloys
- RAM of isotopes
- Allotropes of carbon
- Nanoparticles inc sizes
- lots of quantitative chemistry - especially triple only such as percentage yield, atom economy, gas volumes, and titration calculations 90% likely
- Reactions of metals and acids
- pH and neutralisation
- soluble salts
- electrolysis and half-equations
- bond energies, but more likely drawing/interpreting a reaction profile diagram
- batteries cells, and hydrogen fuel cells - potential 6 marker on evaluating hydrogen fuel cells and rechargeable batteries.
