When an element such as silicon or oxygen is part of a mineral like quartz, it is different from its pure form because it is combined with other elements to form a compound. In the case of quartz, the main element is silicon, which combines with oxygen to form silicon dioxide (SiO2). This compound gives quartz its specific properties and structure.
