Color: Silicon in its pure form is typically dark gray. However, when combined with other elements, it can exhibit different colors depending on the compound it forms.
-
Hardness: Silicon has a Mohs hardness of 7. This means it is relatively hard and can scratch glass and softer materials. However, it is not as hard as some other minerals like diamond or corundum.
-
Clarity: In its pure form, silicon is opaque. However, when combined with oxygen to form silicon dioxide (SiO2), it can occur in various degrees of transparency and clarity. For example, quartz can be transparent, translucent, or opaque depending on impurities and structural defects.
-
Luster: Silicon typically has a metallic luster when it's in its pure form. However, in most of its mineral forms, such as quartz, it displays a vitreous (glassy) luster.
-
Density: The density of silicon varies depending on its form and purity. Elemental silicon has a density of about 2.33 g/cm³. Silicon dioxide (quartz) has a density of around 2.65 g/cm³.
