Ionic and covalent bonds are defined by bond length, and in many real compounds the actual bond length is between the ionic and covalent bond lengths. These bonds can be described as some percentage ionic and some percentage covalent. Si-O (called siloxo) bonds in quartz and opal are mostly covalent. Glass is not mostly covalent because it has alkali fluxes that make it more ionic.
Sialate bonds (Si-O-Al-O, where the aluminum has a alkali atom associated with it) are also mostly (but I believe less so) covalent.

What is the chemical form of quartz?
Quartz is silicon dioxide, SiO2.
What is the chemical composition of quartz mineral?
Quartz is silicon dioxide (SiO2).
What is chemical composition of quartz for electrode?
SiO2 is quartz- a nautural piezo-electric compound when in crystalline form.
Quartz resists chemical weathering more than any other common mineral?
Yes, quartz is highly resistant to chemical weathering due to its strong molecular structure. It is more stable compared to other common minerals such as feldspar or amphibole, which are more prone to chemical breakdown and alteration. This resistance to weathering allows quartz to persist in sedimentary deposits and resist the effects of erosion over time.
Is quartz affected by chemical weathering?
Yes, quartz is relatively resistant to chemical weathering because it is composed of silica, which is a very stable mineral. However, prolonged exposure to certain acids or alkaline substances can slowly dissolve quartz over time.
Is quartz a physical or chemical property?
Quartz is silicon dioxide (SiO2); quartz is not a property.

Does the chemical makeup quartz ever change?
No chemical formulas ever change. If there are different elements in a compound, it ceases to remain the same compound, and becomes a new compound.The chemical formula for quartz is SiO2. That is, always was, and always will be the chemical formula for quartz.

What is a component of granite that is not susceptible to chemical weathering?
Quartz is a component of granite that is not susceptible to chemical weathering. Quartz is a very durable mineral that can resist the chemical breakdown caused by exposure to elements like water and air.
Does quartz have a chemical composition?
No chemical formulas ever change. If there are different elements in a compound, it ceases to remain the same compound, and becomes a new compound.The chemical formula for quartz is SiO2. That is, always was, and always will be the chemical formula for quartz.
What is the most common end product of chemical weathering of quartz is?
The most common end product of chemical weathering of quartz is clay minerals. These clay minerals form from the breakdown of quartz due to exposure to water and other chemical elements over time.
What is chemical composition of quartz for electrode?
SiO2 is quartz- a nautural piezo-electric compound when in crystalline form.
