Week 5/6: Metal Reactivity

Emerging	Foundation	Core	Beyond Core	Accomplished
Can investigate and then determine which everyday metals easily corrode	Can observe and describe single displacement reactions involving metals	Can observe and describe reasons for the reactivity series in metals	Can describe why certain periodic table group elements are more reactivity than other groups and predict the reactivity series down a column	Can describe different crystal structures in metals and how they affect its physical properties

Loss of Electrons = Oxidation     


eg. Al_(s) --> Al³⁺ _(aq)  + 3 e^-


Gain of Electrons = Reduction

eg. O_{2 (g)} + 2e^-  --->    O^2-

DISPLACEMENT REACTIONS (precipitation)







The difference between the SINGLE and DOUBLE displacement reactions is shown below in this image.......

A, B, C & D all represent atoms of elements.....

SINGLE displacement reactions are the first image - A&B are chemically joined to form a compound and C is all on its own. When they react together, B swaps to become chemically joined to C to form a compound and A ends up all on its own.

Example:    HCl  +  Zn -->   H2    + ZnCl

                

DOUBLE displacement reactions are what we were doing last week - where both compounds swap partners.

Example:      CaBr    +    KOH   -->  CaOH   +   KBr

VISUAL: To explain how the reactivity series is used

Week Three: Precipitations

Emerging	Foundation	Core	Beyond Core	Accomplished
Can make then separate a precipitate from a mixture following a very strict series of steps	Can come up with own simple method to separate out precipitate from mixture	Can describe how precipitates form and then demonstrate the separation of them from the mixture	Can use solubility rules to predict which compounds will be soluble/insoluble	Can explain “partial solubility” and what “solubility product” means

Can draw or build a diagram of a molecule given a formula (but not attempting to show electrons in bonds)

Can build physical models and use the physical features of the objects (e.g. how many holes are in the atom ball or ion “key” etc.) to predict the chemical’s formula

Can draw abstract diagrams of molecules including electrons correctly predicting formulae in straightforward cases such as in simple ionic compounds

Can differentiate between covalent and ionic bonds

Can explain hydrogen bonding, van der Waal’s forces and isomerism (structural and stereo) using physical models or abstract diagrams
