Things/Topics you need to know:

Atoms - mass, RFM, charges, shielding, group, period
Elements
Compounds
Mixtures
Structure, Bonding, Properties - ionic,
Carbon stuffs - diamond, graphite, graphene
Balancing equations
Giant covalent
Simple covalent
Methods of separating mixtures - filtration, crystallisation, distillation, chromatography (don’t need much detail)
Models of atoms
– plum pudding JJ Thompson - positive sphere containing electrons
– marsden - gold lead experiment
– Rutherford - concluded electrons orbit an positive nucleus
Ions
Isotopes
Periodic table
– newlands - octaves, didn’t leave gaps, based on atomic weight
– mendeleev - left gaps, groups, increasing atomic number
Group 0, 1 and 7 - properties, configuration and reactivity in each of these
Reactions (metal and oxygen, carbon, neutralisation, can’t remember others)
States of matter
Particle models
Changing states
Metal properties alloys
Fullerenes
Bucky balls
Conservation of mass - mass of products is always equal to mass of reactants
(Gases produced may make mass seem unequal)
Half equations
Moles
Limiting reactants
Concentration
REACTIVITY SERIES
Displacement
Extraction of metals from ores
Electrolysis rules for Aqueous solution
Electrolysis of brine (likely to come up?)
OILRIG
bond energy - Break IN, Make OUT (making is exo, breaking is endo)
Acids
Energy profiles

REQUIRED PRACTICLES
– Making soluble salts
– Neutralisation
– Electrolysis
(Distillation is in my revision guide but my teachers said we don’t need it??)


I can’t think of anything else but feel free to add or reply with anything you’re unsure of and I will try to help!!
GOOD LUCK GUYS
