1. Structure Bonding and Properties
metals
Metal and non-metal
non-metals
Metallic Bonds
E.g. Ag, Cu or Fe
Ionic Bonds
E.g. NaCl, K2S, FeO
Covalent Bonds
E.g. H2O, CO, O2
Properties
Malleable
Ductile
Good Conductors of Heat and Electricity
Properties
High Melting/Boiling pts.
Crystalline solids at room temp
Conduct electricity when dissolved or melted.
Properties
Low melting/boiling points
Liquids or gases at room temp
Do not conduct electricity when dissolved or melted.
Cations are surrounded by a “sea of electrons”
The strong electrostatic attraction between oppositely charged ions
Electrons are transferred
Cations  positive  metals
Anions  negative  non-metals
Valence electrons are shared (1 bond = 2 electrons)
Do not form ions
