Titel 1 Atoms, ions and ionic compounds

Atoms
- Protons
- Neutrons
- Electrons
- Periodic table (what does the numbers mean)

Ions
- Know the charge of different simple ions by using the noble gas rule
- Memorise charges of iron and copper ions (transition metals - noble gas rule cannot be applied)
- Memorise formulae of nitrate, sulfate, carbonate, phosphate, ammonium and hydroxide

Ionic compounds
- Cation and anion
- Lattice
- Melting and boiling points compared to molecules
- Naming

Precipitation reactions
- If a compound contains nitrate, ammonium, sodium og potassium they are soluble in water
- Writing balanced ionic equations
- Writing balanced precipitation reaction including spectator ions

Experiment:
Different precipitation reactions

p. 26-33
p. 38-49
p. 156-157 (about precipitation reactions)

Titel 2 Molecules

Molecules
- Bonding between non-metals
- Covalent bond (sharing of 2 electrons)
- Noble gas rule
- Cross and dot diagrams
- Molecular structure formulae
- Naming (use -di, -tri, -tetra and so on. Different from naming ionic compounds)

Titel 3 Masses and moles

Mass measured in gram
Molar mass - measured in g/mol
Mole - the number of atoms, molecules, ions etc.
The relation: m = n*M
Avogadros number
Calculations with moles (the mole table)
Equivalent masses
Empirical formulae and how to find it from mass percentages.

Concentration measured in mol/L or M (not to be confused with molarmass). Sometimes mol/L is written mol/dm^3
Volume measured in L
The relation: c=n/V
Gasses: 1mol gas has a volume of 24L at rtp.

Experiment:
Finding the amount of water contained in a hydrated salt (water of crystallisation)

p.64--87

Titel 4 Redox reactions

Redox reactions
- Oxidation
- Reduction
- The OILRIG-rule (oxidation is loss of electrons, reduction is gain of electrons)
- Half equations
- Activity series

Experiment:
Activity series - which metal are most reactive and which are most non-reactive
(How to write a scientific report)
