I/GCSE Chemistry- Electrical Conductivity (2/2)

In this I/GCSE Chemistry blog post, we will be looking at the electrical conductivity of different substances as part 2.

Covalent compounds don't conduct electricity

• Covalent compounds don't contain ions, because they make bonds by sharing electrons
• This means they don't have and charge carrier that are free to move- so can't carry an electric current 

Metals are held together by Metallic bonding

• Metals have a giant structure of positive ions surrounded by delocalised electrons 
• The attraction between the positive ions and the electrons is called the matallic bonding
• It is this that gives metals their properties

Metals are good conductors of electricity and heat

• The free electrons carry electrical current and heat energy through the material, so metals are good conductors of electricity and heat 

That is all for part 1!
