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 :)
Why are oxygen and silicon the most common elements found in minerals?
Silicon and oxygen are two of the most abundant elements in the universe. Oxygen will readily bond with silicon and metals to form minerals. Other similarly abundant elements either sank into Earth's interior or tended to form volatile compounds that were driven away from Earth by the solar wind when the planets were still forming.
What are The 2 most common minerals in earths crust?
Quartz and feldspars are the most common silicate minerals of the crust.
What does silicon bond with?
Silicon typically forms bonds with oxygen to create silicon dioxide, commonly known as quartz or silica. It can also bond with other elements like carbon, hydrogen, and various metals to form a wide range of silicon-based compounds.
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

What is the result when two single chains of tetrahedra bond to each other?
When two single chains of tetrahedra bond to each other, they form a double chain structure. This arrangement creates a stronger and more stable crystal lattice compared to the individual chains.
When two single chains of tetrahedra bond to each other the result is called a what?
When two single chains of tetrahedra bond to each other, the resulting structure is called a double chain silicate. These structures typically involve each tetrahedron sharing three oxygen atoms with adjacent tetrahedra, forming a linked double chain. Examples include amphiboles and pyroxenes.
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
Double-chain silicates are formed when?
Chain silicates have interlocking chains of silicate tetrahedra. When adjacent tetrahedrons share either two oxygen's to continue the chain, or three oxygen atoms to connect also to a second chain, double chains are formed.

Why does more silica make lava flow slow?
Silica-rich lava has higher viscosity, which means it is thicker and flows more slowly. The high silica content causes the lava to be more resistant to flow, leading to a slower movement. This can result in the formation of more explosive eruptions, like those seen with volcanoes such as Mount St. Helens.
What are the monomers in minerals?
The monomers in minerals are atoms or ions. These monomers can bond together through chemical reactions to form crystal structures, which are the building blocks of minerals. Examples of monomers in minerals include silicon (Si) and oxygen (O) in the case of silicate minerals.
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
