Metals
- Bonding
- Metallic
- tightly packed layers
- lattice
- tightly packed layers
- 'Sea' of delocalised electrons
- outer electrons separate from atoms
- free to move through whole structure
- outer electrons separate from atoms
- Metal atom centre
- positively charged
- attracted to delocalised electrons
- positively charged
- Metallic
- Physical properties
- conductors of heat
and electricity
- heat
- D/L electrons gain kinetic
energy
- move faster so transfer energy
through-out metal
- move faster so transfer energy
through-out metal
- D/L electrons gain kinetic
energy
- electricity
- D/L electrons create charge
- D/L electrons free
to move
- D/L electrons create charge
- heat
- High melting point
- strong attraction between +
core and D/L electrons
- strong attraction between +
core and D/L electrons
- Malleable
- centres are able to slide
over each other
- D/L electrons keep
structure together
- centres are able to slide
over each other
- Dense
- many atoms packed
into small space
- tight lattice structure
- many atoms packed
into small space
- conductors of heat
and electricity
