Remember that the lattice arrangement is giant - for example, a single grain of salt may contain 1.2 × 10 18 (1,200,000,000,000,000,000) ions. The lattice arrangement continues in three dimensions.

Ionic compounds are also known as electrovalent compounds. The chemical bond formed by the transfer of electrons from one atom to another is known as Ionic bond. These compounds contain ions. Through ...

Listen to the full series on BBC Sounds. Ionic compounds have high melting and boiling points, so they are in the solid state at room temperature. See the study guide on the three states of matter to ...

Ionic liquids are generally regarded as solvents, but these modular, tunable compounds have far greater technological potential. With a coat of silver, they become ideal materials for the liquid ...
