Covalent bonding

HideShow resource information
What is a covalent bond
When non metals share PAIRS of electrons
1 of 7
What are properties of covalent molecules
Low boiling point, does not conduct electricity, usually a gas or liquid
2 of 7
Why do covalent bond have low boiling points
The bonds between atoms are strong but there are weak intermolecular forces
3 of 7
Name two giant covalent structures
diamond and graphite
4 of 7
Why can graphite conduct electricity
It has delocalised electrons as it only uses 3 of 4 carbon bonds
5 of 7
Why is graphite used as a lubricant or in pencils
It is arranged in layers that are held together with weak forces of attraction
6 of 7
Why can diamond not conduct electricity
It has no free electrons as all 4 carbon bonds are used up
