Quartz.
Feldspar.
A silicate sheet has one cleavage plane, which allows it to split easily along this flat surface. This cleavage plane is a result of the structure of silicon and oxygen atoms arranged in sheets within the mineral.
Silicon typically exhibits cleavage rather than fracture. Silicon has a crystal structure that allows it to cleave along specific planes with clean breaks, unlike other materials that exhibit more random fracturing patterns.
cleavage, if a natural property of the mineral (e.g. mica); or a fault, such as in a gemstone.

Yes, all different samples of that mineral will have the same cleavage.

Cleavage is the tendency of materials to split along definite structural planes, yielding smooth surfaces. An example is shales or shists.
The mineral cleavage is made up of many other particles to form a rock when the rock cleavage is just a rock.

The name of a mineral that splits along flat surfaces is called mica. Mica's cleavage planes allow it to be easily split into thin sheets.
