What are silicates made of?
Silica tetrahedra, made up of silicon and oxygen, form chains, sheets, and frameworks, and bond with other cations to form silicate minerals.
Describe the six main crystalline structures of silicate minerals?
Isolated tetrahedra silicates do not link with other silicon or oxygen atoms Ring Silicates form by sharing oxygen atoms Single Chain Silicates form a chain when sharing oxygen atoms Double Chain Silicates form when two or more single chains of tetrahedra bond to each other Sheet Silicates form when each tetrahedron shares three of its oxygen atoms with other tetrahedra Framework Silicates form when each tetrahedron is bonded to four other tetrahedras :)
What is SiI4?
It's silicon-oxygen tetrahedra, it's covalent bond of a quartz, crystal.
What are The 2 most common minerals in earths crust?
Quartz and feldspars are the most common silicate minerals of the crust.
What is the relationship between the way in which silicon-oxygen tetrahedra bond in micas and the characteristic cleavage of micas?
The silicon-oxygen tetrahedral bonds that make up mica form sheets that lay on top of each other and are easily separated, as sheets, which gives mica one direction of cleavage
What are silicates made of?
Silica tetrahedra, made up of silicon and oxygen, form chains, sheets, and frameworks, and bond with other cations to form silicate minerals.
What is the result when two single chains of tetrahedra bond to each other?
Double chain silicate
When two single chain of tetrahedra bond to each other the result is?
double chain silicate
What is the result of two single chains of tetrahedra bond to each other?
double chain silicate
Why does more silica make lava flow slow?
In rocks lava with a high silica content the silica starts to form a covalent network, where the silicate groups continously bond together.
Is halite constructed of silica tetrahedra bonded by covalent bonds on three corners and an ionic bond on the remaining corner?
Halite is rock salt, NaCl, not a silicate. In the halite structure each sodium is surrounded octahedrally by 6 chloride ions, and each chloride is surrounded octahedrally by 6 sodium ions

What is SiI4?
It's silicon-oxygen tetrahedra, it's covalent bond of a quartz, crystal.
How many covalent bonds are ther in one molecule of silica?
Silica has two double bonds.The compound is also called silicon dioxide (SiO2); each oxygen is attached to the silicon by a double bond (pi bond).This gives silica an overall linear shape. O=Si=O
What are The 2 most common minerals in earths crust?
Quartz and feldspars are the most common silicate minerals of the crust.
Why the silica cement equipped with mold able?
Silica cement is a refractory mortar that is suitable for laying silica brick. It is equipped with an AX moldable to make it easily bond to itself and other fibrous insulations.
What is the most abundant element in Earths continental crust by weight is?
oxygen is the most abundent element present i n the earth crust by weight.Because it makes covelent bond with silicon to form silicates ,which react with other minoer elements of the earth to foem a huge number of silicate minerals.
