Describe the effect of concentration, particle size, catalysts and temperature on the rate of reactions
Describe and explain the effect of changing concentration in terms of frequency of collisions between reacting particles
Describe and explain the effect of changing temperature in terms of the frequency of collisions between reacting particles and more colliding particles possessing the minimum energy (activation energy) to react
Describe how concentration, temperature and surface area create a danger of explosive combustion with fine powders (e.g. flour mills) and gases (e.g. methane in mines)
Redox - Describe oxidation and reduction in chemical reactions in terms of oxygen loss/ gain (Oxidation state limited to its use to name ions, e.g. iron(II), iron(III), copper(II).)
Define redox in terms of electron transfer, and identify such reactions from given information, which could include simple equations
Define and identify an oxidising agent as a substance which oxidises another substance during a redox reaction and a reducing agent as a substance which reduces another substance during a redox reaction
Atoms, elements and compounds - structures and bonding
-
-
-
Atomic structure
-
The proton number gives the number of protons or electrons and the nucleon number is the number of protons and neutrons together
The Periodic Table
Periodic trends
-
Relationship between group number, number of outer-shell electrons and metallic/non-metallic character
-
Transition elements
A collection of metals having high densities, high melting points and forming coloured compounds, and which, elements and compounds, often act as catalysts
Noble gases
Group VIII or 0, as being unreactive, monoatomic gases and explain in terms of electronic structure

Experimental techniques
measurment
time - stopwatch
temp - thermometer
mass - digital balance
volume approx. - measuring cylinders
volume accurate - pipets/ burettes

Chromatograms
-
Every day life of purity
to make sure drugs have the right amount of chemicals to fix peoples ills and to make sure food wont kill you
