Crystal structure is a concept used to describe the three dimensional arrangement of atoms in a solid.
Lattice arrangements are representations of atoms in a three dimensional structure very often repeated over and over again with exactly the same symmetry.
Ionic radius can be defined as the size of the radius of an ion from the nucleus to the valence electron. The ionic radius is difficult to measure due to the overlap of ions in a lattice structure.
Bond strength is the measure of how strong a bond is in terms of the energy needed to make and break the bond
