metallic bonding model
strong electrostatic forces between cations in fixed positions and delocalised electrons in 3D lattice
properties
good conductor of electricity= have free-moving delocalized electrons that carry charge.
malleable= layers that can slide without breaking the bonds.
ductile=atoms can move without breaking.
lustrous=Metals reflect light because of there free electrons
alloys
prepared by meliting metals and/or other mixtures together and then cooling it
Reactivity with water
metal+ H2O —- metal hydroxide + H2
reacitivity with oxygen
metal + oxygen —- metal oxide
reactivity with acids
metal + acid —- ionic salt + H2
