1
New cards

metallic bonding model

strong electrostatic forces between cations in fixed positions and delocalised electrons in 3D lattice

2
New cards

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

3
New cards

alloys

prepared by meliting metals and/or other mixtures together and then cooling it

4
New cards

Reactivity with water

metal+ H2O —- metal hydroxide + H2

5
New cards

reacitivity with oxygen

metal + oxygen —- metal oxide

6
New cards

reactivity with acids

metal + acid —- ionic salt + H2
