Q
Why do most good conductors of electricity
A
The delocalised electrons are free to move when a potential difference is applied across
1
Q
What can a metals be described as
A
A giant structure of positive ions surrounded by a sea of delocalised electrons
2
Q
Why are metals Malleable and ductile
A
The layers of positive ions can easily slide over one another and take up different positions.
The delocalised electrons move with them so the metallic bonds are not broken
