Atomic structure

Atomic structure

1. atoms

   • elements
   • substances
   • properties
   • symbols
   • periodic table
     • groups
     • metal/ non-metal
     • semi-metals
   • compounds
     • chemical bonds
   • nucleus and electrons

2. chemical equations

   • reactants and products
   • word/ symbol equations
   • balanced
   • law of conservation of mass
   • state symbols
     • solid
     • liquid
     • gas
     • aqueous solution

3. separating mixtures

   • compounds
     • fixed composition
     • chemical reactions to separate
     • chemical bonds
   • mixtures
     • no chemical bonds
     • no fixed composition
     • separated more easily
   • filtration
     • soluble and insoluble
   • crystallisation
     • evaporation
     • salt solution
     • crystals
   • distillation
     • heating
     • condenser
     • receiving vessel
     • flask
     • fractional and simple
   • chromotography

4. fractional distillation

   • miscible and immiscible
   • different boiling points
   • fractionating column
     • glass column/ beads
   • condenser
   • condensation
     • bottom of fractionating column= higher boiling point
     • higher fractionating column= lower boiling point

5. paper chromatography

   • mixtures in solution
   • capillary tube
   • pencil line
   • solvent and solution
   • more soluble=further up the paper

6. history of the atom

7. structure of the atom

8. ions, atoms and isotopes

9. electronic structures
