All of a mineral’s physical and chemical properties are caused by
Some minerals have special properties such as:
The physical properties can be used to identify minerals. Which physical property is the least
reliable and why?
Most common minerals belong to the SILICATE family, and are made up various arrangements of the
silicon-oxygen tetrahedron, a 4-sided unit of one silicon atom surrounded by 4 oxygen atoms. Its looks
