This gives a sheet silicate. Examples of minerals with this structure include kaolinite and talc.
When one oxygen atom shares two pairs of electrons with another oxygen atom, they form a double bond between them. This results in the formation of O2, which is the oxygen molecule commonly found in the Earth's atmosphere.
There are 6 electrons in the outermost energy level of an oxygen atom. In a water molecule, oxygen shares electrons with two hydrogen atoms to form covalent bonds, achieving a full outer shell with 8 electrons (octet rule). Oxygen shares one electron with each hydrogen atom to complete its outer shell.
Eight. Oxygen has 6 electrons and shares two more with the hydrogen atoms in covalent bonds
The atomic structure of water (H2O) consists of two hydrogen atoms bonded to one oxygen atom. Oxygen shares electrons with the hydrogen atoms, forming covalent bonds. Each hydrogen atom shares its electron with oxygen, allowing oxygen to have a full outer shell of 8 electrons, satisfying the octet rule.
In CH2O, there are a total of 12 valence electrons. Carbon shares 4 electrons, each hydrogen shares 1 electron, and oxygen shares 2 electrons. Therefore, a total of 10 electrons are being shared in CH2O.
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 :)
A silicate mineral that shares it's oxygen atom with another silica tetrahedron, forming a chain of tetrahedra. Single chain silicates include a group called the pyroxenes.
Isolated tetrahedra are linked with silicate minerals such as olivine and garnet, where each tetrahedron shares no oxygen atoms with neighboring tetrahedra. This results in these minerals having higher densities and more complex crystal structures compared to other silicate minerals.
Garnet is an example of a mineral that has a basic structure consisting of isolated tetrahedra linked by atoms of other elements. In garnet, each tetrahedron shares oxygen atoms with neighboring tetrahedra, creating a three-dimensional framework. The cations occupying the spaces in between the tetrahedra give garnet its characteristic structure and properties.
I was confused by this question- if each [SiO4] tetrahedron is bonded to four other tetrahedra then each silicon has half a share of 4 oxygens- so the formula is SiO2- but that is not a silicate, that is silica, but thenIremembered mineralogists classify silica as a silicate!.If the odd silicon atom is replaced with say aluminium then you could form a network (3D) anion where there are both [SiO4] and [AlO4]- tetrahedra linked at the corners. The complexity of these structures is difficut to describe in words but there are voids in n the structure where the balancing cations sit. These minerals are called tectosilicates and include feldspars which are quite prettily colored. Tectosilicates are common in nature. Feldspars have formulae that have 2:1 ratio of O to the total of Si and Al atoms, for example KAlSi3O8,where 1 Si in four has been substituted for Al.
The type of silicate with the greatest proportion of oxygen atoms shared by pairs of adjacent tetrahedra is the phyllosilicates. In phyllosilicates, each tetrahedral unit shares three oxygen atoms with neighboring tetrahedra, resulting in a two-dimensional sheet structure. This high degree of sharing leads to their unique properties, such as flexibility and perfect cleavage. Examples of phyllosilicates include minerals like mica and talc.
