Ionic bonds are formed between metals and non - metals. Metallic Bonding. In metals, positive metal ions are held together by electron clouds. This is known as metallic bonding. These electrons are free to move through the structure, this is why metals conduct electricity. This can explain the change in melting points as you go down group I.

Multiple bonds are stronger than single bonds between the same atoms. The enthalpy of a reaction can be estimated based on the energy input required to break bonds and the energy released when new bonds are formed. For ionic bonds, the lattice energy is the energy required to separate one mole of a compound into its gas phase ions.
