C2 18 Metallic Bonding And Transition Metals

Question 1

Describe and explain the properties of metals limited to malleability and the ability to conduct electricity

Answer 1

The delocalised electrons move around randomly between the positive ions in all directions. If a potential difference is applied across a piece of metals, the electrons start to drift in one direction. This movement of electrons is an electric current

Layers of positive ions in a metal can slide over each other if a large force is applied to a piece of metal. The ions are still held together by the sea of electrons so metal spreads out instead of breaking, it is malleable.

Question 2

Describe the structure of metals

Answer 2

It is a regular arrangement of positive ions surrounded by a sea of delocalised electrons
