Respuesta :
The answer to this question would be: covalent bond
Silicon dioxide or SiO2 is made of silicon which is a metalloid and oxygen which is a gas. The bond that the molecule made is a polar covalent bond because silicon is not a real metal. Silicon dioxide is a polymorph that has many different kinds of crystal form.

Answer:
Covalent bonds.
Explanation:
Quartz is a common mineral found in the earth's crust. Chemically it is composed of a silicon(Si) and oxygen (O) and has a formula SiO2, also known as silica or silicon dioxide.
The bonds formed between elements can be broadly classified into four types:
Ionic, Covalent, metallic and Van der waals
In the case of quartz, the each Si atom is covalently bonded to four O atoms and each O atom is forms a covalent bond with 2 Si atoms resulting in a hexagonal crystalline form. Covalent bonds are the strongest which explains why SiO2 has a high melting point.
