Did you know?

WebGiant covalent structures have strong covalent bonds throughout the structure. Lots of energy is needed to break the many covalent bonds between atoms so they have high melting and boiling points. 2 Strong covalent bonds hold the atoms in the molecules together. There are only weak intermolecular forces between the molecules.

WebDescribe the Properties of a Simple Molecule. • The bonds within the molecules are strong covalent bonds. • The forces of attraction between the molecules are much weaker and therefore little energy needed to overcome the forces between the molecules and so the melting and boiling points are relatively low.
