Electron structure of ions

Same as the nearest noble gas

Giant structure

A huge 3D network of atoms or ions

lattice

Regular arrangement of particles.

Giant ionic lattice

A huge, 3D, regular structure of oppositely charged ions, held together by electrostatic forces.

Examples of Ionic compounds

NaCl, MgO

Limitations of dot and cross diagram

Looks like the compound only contains a few ions

Limitations of a dot and stick diagram

Looks like each ion is only attracted to a few other ions

Limitations of a 3D diagram

Looks like it only contains a few ions
