Chemistry C2 - Metallic Structures

HideShow resource information

Metal properties are all due to the sea of free electrons

1) Metals all consist of a giant structure 

2) Metallic bonds involve the all-important 'free electrons' which produce all the prpoerties of metals. These delocalised (free) electrons come from the outer shell of every metal atom in the structure 

3) These electrons are free to move through the whole structure and so metals are good conductors of heat and electricity 

4) These electrons also hold the atoms together in a regular…
