The arrangement of the mineral's atoms
Explanation:
The arrangement of atoms in a mineral determines both the physical and chemical property of such a substance.
Minerals are naturally formed inorganic chemical substances with a definite and ordered atomic arrangement. Most minerals are usually solid in nature.
Minerals have an ordered atomic arrangement and this dictates its properties.
For example, the luster minerals can be attributed to the faces of the ordered crystals that makes up the mineral.
Rocks breaks in certain fashion due to the nature and the ordered structure of the atoms making up their minerals.
