You should be able to (higher tier in bold):
recall the formulae of elements and simple compounds in the module
represent chemical reactions by word equations; write simple balanced equations
and use state symbols (s), (l), (g) and (aq)
write balanced equations to describe and explain a wide range of reactions
including ionic equations
The structure of atoms
You
Elements and the periodic table
You should be able to:
C3.02 recall that there are approximately 100 elements in the periodic
table arranged in order of increasing
atomic number and recall that
elements are the building blocks of all materials
C3.03 recall the position of metals and non-metals in the periodic table
C3.04 locate the positions in the periodic table of the alkali metals (group 1), the halogens (group 7), the
noble gases (group 0)
C3.05 understand how the electron shell are filled in the atoms of the first
twenty elements in the periodic table
C3.06 understand the connection between the number of outer electrons and the
position of an element in a group in the periodic table
C3.07 understand that the reactions of elements depend upon the arrangement of
electrons in their atoms
C3.08 recall that there is a gradual change in the properties of the elements from the
top to the bottom of each group
C3.09 understand that elements in the same group of the periodic table have
similar chemical properties, for example by the halogens
The properties of halogens
You should be able to:
C3.10 recall that fluorine, chlorine, bromine, and iodine are halogens
C3.11 recall the colours, the trend in boiling points and the physical states of the halogens at room temperature
C3.12 describe the reactions of chlorine with sodium and iron
C3.13 describe the change in reactivity of the halogens with increasing
atomic number, as shown by their displacement reactions with solutions of other
halides
C3.14 describe the uses of chlorine
in water purification and
bleaching
C3.15 recall the use of iodine solution as an antiseptic
Rates of reaction
You should be able to:
C3.16 recall that there is a great variation in the rates at which
different reactions take place
C3.17 understand that the rate of chemical reaction increases if
the temperature is increased
the concentration of reactant is increased
the surface area of a solid reactant is increased
a catalyst is used
C3.18 describe experiments to investigate the above effects
C3.19 understand that reactions occur when particles collide
C3.20 understand that the rate of a reaction is increased by
increased frequency of the collisions
greater energy of the collisions
C3.21 describe how the rates of enzyme catalysed reactions vary with temperature
and pH
