they bond the silica tetrahedron exist as single units bonded to positively charged ions
Silica tetrahedra, made up of silicon and oxygen, form chains, sheets, and frameworks, and bond with other cations to form 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 :)
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.
Quartz and feldspars are the most common silicate minerals of the crust.
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.

Silica tetrahedra, made up of silicon and oxygen, form chains, sheets, and frameworks, and bond with other cations to form silicate minerals.
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 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.
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
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.

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.
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.
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
