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.

An Ionic bond is formed when one of the atoms can donate electrons to achieve the inert gas electron configuration and the other atom needs electrons to achieve the inert gas electron configuration.

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 ...

The study of crystal growth and characterisation of fluorite-like compounds has garnered significant attention owing to their unique structural features and promising functional properties. These ...
