I/GCSE Chemistry- Giant covalent

Bonding

· igcse chemistry

In this I/GCSE Chemistry blog post, we will lookg at the different example of covalent bondings such as silicon and diamond.

Diamond (and Silicon)

broken image
  • Each Carbon atom forms 4 strong covalent bonds with other atoms to give a tetrahedral structure.

High melting and boiling points

  •  A lot of energy is required to break the many strong bonds, hence the high melting and boiling points.

Hard Substance 

  • The many strong bonds each require a large force to break them.

Doesn't conduct electricity

  • No free electrons to carry a current when a potential is applied. 
  • Insoluble

Graphite

  • Each Carbon atoms forms 3 strong covalent bonds with other Carbon atoms, resulting in a layered structure.
  • One spare electron is delocalised between the layers.
  • The layers are held together by weak intermolecular forces.

High Melting and Boiling points

  • The many strong bonds require a lot of energy to break, hence the high melting and boiling points.

Soft Substance

  • Little force is needed to overcome the weak intermolecular forces.

Conducting Electricity

  • The free delocalised electron is able to carry a current when a potential is applied.

That is all!
