Metals
# formula consists only of symbol of metal-atoms
# metallic lattice
# positively charged "metal-ions" and freely moving elektrons
# metal bond
# conduct electricity in solid and liquid phase

Slide 5 - Slide

Molecular substances (7.3)
# molecules in a molecular lattice
# only symbols of non-metals in the formula
# atomic or covalent bond within molecules
# Van der Waals bonding between molecules
# Hydrogen bond (between, OH- and or NH-groups!)
# No charged particles which can move freely => cannot conduct electricity in any phase!

Slide 6 - Slide

Salts
# formula consists of symbols of non-metals and metals
# Ionic lattice
#ionic bond
# Negatively charged non-metal ions and 
positively charged metal ions.
# Conduct electricity in liquid and dissolved (aq) phase. (in solid phase the charged particles cannot move!)
