The chemical formula and crystal lattice of a mineral define its chemical properties and physical properties.
This is because the chemical formula specifies the categories and amounts of the chemical element in a mineral.
While the crystal lattice of a mineral is used to determine the physical properties of a mineral.
The crystal lattice is the structure of how the atoms are organized and bonded together.
Both crystal lattice and the chemical formula of a mineral can only be known through laboratory examination.
Hence, in this case, it is concluded that the chemical formula and crystal lattice are important features of a mineral.
