Chemistry
Chemical Reaction
Combination
Fe + S >> FeS
Precipitation
KI + PbCl2 >>> PbI (s) + KCl (aq)
Decomposition
Na2CO3 >> Na2O + CO2
Displacement
Fe + AgCl
Depends on Reactivity
Combustion
C + O2 >> CO2

Atomic Structure
Electron Structure
Shell
p n e
relative mass
relative charge
Ions
Atoms - Lost or gained electrons
Often form full outer shell
Valence
IE
Energy to remove 1 electron
FACTORS
p
inner electrons
distance
Bonding
types
Covalent
Shared pair of electrons
protons in the nucleus of each atoms
Giant
High BP
Simple
Low BP
because there are weak inter-molecular forces
Diagrams
Dative - 2 electrons from ONE atom
Complex Ions - SO4, NO3, OH
Octet rule - 8
STEPs -
make a bond between each atom
fill the outer atoms
make bonds to satisfy everyone
decide where is electron is FROM
Averages - two of the same structure
RESONANCE
Ionic
Cation Anoion
Conduct - Sol or Molten
ions can carry charge - move (mobile)
High BP -
Metallic
sea of delocalised e
lattice of metal cations
Conduct electricity
sea of DLE can move
according to charge
