The mineral property that depends on bond type and the spacing of atoms within a crystal is hardness.

Here's why:

* Bond type: Stronger bonds, like covalent or ionic bonds, require more energy to break, making the mineral harder. Weaker bonds, like van der Waals forces, result in softer minerals.

* Spacing of atoms: Closer spacing of atoms within a crystal structure results in greater resistance to deformation, leading to higher hardness.
