CIE A2 Chemistry
, 5.1 Lattice Structure
Ionic compounds: solids
arranged alternatingly in
a regular and orderly
cubic pattern in three
dimensions with the
same orientation; unit
cells
The three dimensional
array formed by the unit
cells of a crystal is called
lattice.

CIE A2 Chemistry
, 5.1 Lattice Structure
Formation of crystal lattice depends on the
attraction between opposite ions in achieving
the highest stability
Higher attraction, higher stability
The ions will tend to organise themselves to
reach the highest stability with a minimal
repulsion forces
