Atomic structure
- protons,
neutrons and electrons
- nucleus

arranged in shells
- how
reactivity depends on electron arrangement

Periodic table
- about
the 100 elements arranged in order of ascending atomic number
- the
position of the metals and non-metals
- the
positions of Gp I, VII & 0
- group
properties and trends

Halogens
- their
properties (colour, boiling point and physical state at room temperature
- the
reaction of chlorine with sodium and iron
- halogen
displacement reaction
- uses
of chlorine and iodine

Rates of reaction
- how the rates change when
- the
temperature is increased
- the
concentration of reactant increases
- the
concentration of a solid reactant increases
- a
catalyst is used
|

Collision theory
- rate
of a reaction can be increased by
- increased
frequency of collisions (more collisions more often)
- greater
energy of the collisions
- how
the rate of enzyme catalysed reactions vary with temperature and pH

Atoms and Isotopes
- each
element has an atomic number and atomic mass
- isotopes
have the same number of protons and electrons but the number of neutrons
varies
- calculate
the relative atomic mass based on the abundances of each isotope

Chemical bonds
IONIC
- how
ionic bonds form between metals and non-metals
- formation
of ionic bonds involves electron transfer and the formation of charged
ions
- the
properties of ionic compounds- HIGH MELTING POINTS, CONDUCT ELECTRICITY
WHEN MOLTEN OR IN SOLUTION, GENERALLY SOLUBLE IN WATER
|
Volume 2 p44

Chemical bonds
COVALENT
- how
covalent bonds form between atoms of non metals
- covalent
bonds involve the sharing of electrons
- that
covalent compounds fall into two groups-simple covalent and giant
covalent
- simple
covalent have low melting points and cannot conduct electricity
- giant
covalent (diamond, graphite and silicon dioxide) have high melting
points, poor solubility and cannot conduct electricity (except for
graphite)

Energy transfers
during reactions
- reactions
can give out heat (EXOTHERMIC)
- or
take in heat (ENDOTHERMIC)
- when
bonds are broken energy is required and when bonds are formed energy is
released, it is the balance between these that means the reaction is
endo or exo

equations
- to
calculate the Relative Atomic Mass Ar
- calculate
the masses of products and reactants using equations
- working
out formulae

chemical reactions by word equations: write simple balanced equations
and use the state symbol (s), (l), (g) and (aq)
write balanced
equations to describe and explain a wide range of reactions including ionic
equations
